Commercial Wireless Solutions Week | Meet the Team: John Yania, Filters Product Line Manager

by Jaymie Murray 18. February 2015 14:00

In his role as Filters Product Line Manager, John Yania engages with customers to find the best filter solution to suit their project requirements. For customers in the telecom and wireless communications industry, John uses his extensive experience and product knowledge to create custom bandpass, bandreject, and duplexers / diplexers filters for broadband networks, communication uplink / downlink systems, spectrum clearing, as well as many other applications. 

Q: What is your role, how long have you worked at API, and what does your position entail?

A: I was one of the founders of FSY Microwave in 1983, which was then acquired by Spectrum Microwave in 2002, which became API a few years ago.  I have been in this field for over 30 years and with API since they expanded their RF & Microwave business.  

I’m the Filter Product Line Manager in API’s RF, Microwave & Microelectronics (RF2M) group.  In this role, I work directly with our customers to create fully customized filters that are optimized to fit their needs, whatever they may be.   

Q: What are some of the custom needs our customers have? 

A: None of our filters are standard, off-the-shelf products.  Every filter we make is created specifically for our customers to fulfill their needs.  Whenever I work with a customer, I try to engage with them early on in the process to get a better idea of their priorities so we can create the design based on those needs.  Sometimes cost is the most important factor, sometimes size, rejection, insertion loss, or another electrical parameter is paramount.  If the filter is going to be used for defense or space applications, a fighter plane or a satellite for example, reliability is obviously going to be the prime concern.  

For our commercial customers, I’ve found that they put a lot of emphasis on quick turnaround times.  If a company wants to be first to the market with a brand new idea, they need to get their products manufactured as soon as possible.   Commercial customers tend to want much more compressed development times and a significantly higher volume of filters compared to our defense customers, but API has the expertise and infrastructure in place to be able to fulfill these needs.

Q: What are the commercial applications for our filters? 

Our filters can be found in a wide range of commercial products, from medical testing instruments to GPS equipment.  In cable TV applications, our filters are used to ensure customers only receive their package’s channels.  For utility companies, API’s filters are used for remote meter reading.  These readings can be sent directly to the utility, or can be scanned by a van passing through the area.  Our Rancho Cordova, CA location mainly manufactures filters that are used in wireless and other demanding commercial applications.  We also provide filters used in location tracking for our commercial as well as defense customers.  

Q: What differentiates our products from what our competitors offer?

A: Over the years, we’ve created over 10,000 different models for our customers.  It’s highly unusual for us to sell the same exact part to two different customers.  I think that is what really sets us apart from our competitors.  We partner with our customers to create a filter that fits their exact specifications, rather than taking an existing product and then adapting it.  We don’t subscribe to the “one size fits all” philosophy that some of our competitors have, and that really does add value to our proposition.  

We also offer our customers the option of having their filters produced at our low cost manufacturing facility in Mexico.  By utilizing our production team in Mexico, our customers can cut costs without sacrificing quality.  The filters produced there are exactly the same as the ones produced in the US, but we are able to pass the labor savings on to our customers.

Commercial Wireless Solutions Week Case Study: API's Filter Mitigates BAS Interference for Major Telecom Company

by Jaymie Murray 16. February 2015 15:27

Over the years, API Technologies has built a solid reputation among wireless service providers by solving even the most challenging interference issues. API's range of filter designs for the telecom industry offer a host of customizable topologies and models that can be modified and adapted to meet the specific needs of the customer. One such customer, a major telecom company, struggled with significant and persistent issues concerning Broadcast Auxiliary Service (BAS) interference in Electronic News Gathering (ENG) trucks. After several other companies tried and failed to rectify the situation, the telecom company engaged API Technologies. The result? Find out in this case study:

Case Study: API Technologies’ Filter Mitigates BAS Interference for Major Telecom Company Challenge A major telecommunications company that provides wireless, internet, and digital television services was experiencing a persistent and complex issue with television Broadcast Auxiliary Service (BAS) interference. One particular major network affiliate in a large metropolitan area was having severe problems with their Electronic News Gathering (ENG) trucks. The frequencies used by these trucks to transmit news video back to the station were experiencing severe interference problems. The interference was so severe that the company had to contact several filter manufacturers to attempt to mitigate the situation, to no avail. However, when they contacted API Technologies, a company that had previously successfully solved a similar problem by using an Advanced Wireless System (AWS) and Broadcast Auxiliary Service (BAS) interference mitigation filter (CMN719 2.1 GHz Band Reject Filter), API was confident that they could solve this issue. Solution After only three months of design iterations and lab calculations, API’s first filter prototypes were sent out for field testing. While a significant improvement was seen, it was not quite enough to allow the BAS receivers to function properly. The prototype filters were then sent back to API, minor re-tuning adjustments were made, and the units were shipped back to the customer, all within the span of one week. The interference problem was identified as Out Of Band Emissions (OOBE) and was remedied with API’s customized CMN719 2.1 GHz Band Reject Filter. Result Within a month the telecom company had sent out a directive to all of their regional offices which described this problem, API’s filter solution, and the requirement to install the filters at all cellular sites that may be impacting the BAS receive frequencies. Within only eight months, affiliates in nine different regions ordered over a thousand filters to finally solve their BAS interference issues.After solving this major issue for this customer, it brought to light an interesting possibility: if this telecom provider was experiencing this problem, there is a good chance that television networks and their affiliates around the country are being affected by OOBE without even realizing it or knowing that it can be easily rectified using API’s CMN719 2.1 GHz Band Reject Filter. API's CMN719 2.1 GHz Band Reject Filter API’s reputation for designing and delivering some of today’s most challenging bandreject filters is the reason why engineers trust us with their designs. Choosing from a wide assortment of topologies, including lumped element, cavity, ceramic, waveguide and suspended substrate, our engineers match the optimum topology to your requirements. The customizable CMN719 2.1 GHz Band Reject Filter features 2030 to 2109.5 MHz passband, 1.60 dB max insertion loss, 16 dB min return loss, and 60 dB min    2110.6 – 2121.5 MHz rejection.

Data Privacy & Protection Week: Meet Richard Mundy, SSIA Security Manager

by Karen Gait 27. January 2015 11:38

As part of our Data Protection Week we introduce the SSIA Security Manager Richard Mundy, who is responsible for the overall data protection and information security for the SST product line. As technical sales director and security manager, Richard is responsible for managing key sales accounts as well as information and overall security at the SST location.

Q: What is your background and when did you start at SST?

A: As a teenager I completed an apprenticeship with Square D Ltd during which achieved a Higher National Diploma in Mechanical Engineering. This resulted in a role as a design engineer. I have been a senior development engineer / assistant chief engineer at Philips TMC designing telephone equipment and PABXs where I also gained my Bachelor of Science in Electrical and Electronic Engineering. After holding a variety of senior management roles at Dowty Limited and Menvier, I joined SST as the technical director (which has evolved into the technical sales director role) I also took on the additional responsibility of the security manager. 

Q: How important is data protection in your role?

A: Data protection is vital for all companies in order to protect sensitive competitive information.  This ranges from critical design information through to financial and operating information for companies. Every company also has an obligation to protect an individual’s identity and information, whether this be employee, customer, or supplier. With our role in the industry in which we operate this is particularly important as we handle classified information on behalf of the UK government and NATO organisations. This is a full time commitment to keeping aware of the latest risks and vulnerabilities, taking appropriate action to mitigate these threats, and managing the IT infrastructure to provide the best possible protection. 

Q: Is data protection and information security important away from the workplace?

A: For a great deal of these issues highlighted for companies to consider, there are parallels for individuals to consider in their home life.  The consequences of identity theft are well publicised and can cause significant financial or other hardships.  We should all be well aware of looking after our credit card and similar personal details nowadays, but how far do we take this really?  Do we adequately destroy bill receipts?  Are we careful of what we throw into the general refuse bin?  Do we change default passwords on home WIFI networks and similar equipments? Maybe not as often as we should... it is critical that we are equally vigilant in our personal life as in our work environment.
