Signal Jamming is the New Black: How LDMOS Technology Blocks Prisoners from Using Cell Phones

by Jaymie Murray 7. October 2015 09:25

Prisons and other correctional facilities are facing an increasingly daunting technological challenge. Contraband cell phones smuggled in by prisoners pose a tremendous security threat to the safety of both staff and inmates alike. While security screenings are designed to identify and dispose of such contraband before it enters a secure facility, at times these phones can slip through the cracks and end up in a cell along with an inmate. Correctional facilities are in need of a solution that prevents contraband cell phones from being used from within the prison walls. The Communications Band Signal Jamming Power Amplifier from API Technologies is that solution. The amplifier operates on the standard communication band frequencies, jamming cell phone signals and rendering the phones inoperable.

Cell phone smuggling has become an increasingly unmanageable problem for prisons and other correctional facilities. These phones pose a significant security threat and can be used to endanger the welfare of correctional workers as well as other inmates, or to coordinate escape attempts. While the first line of defense against this threat is to prevent the phones from entering correctional facilities in the first place, many often slip past security screenings and wind up in the hands of inmates. It has become increasingly apparent security screenings aren't sufficiently mitigating this threat, and there is a significant need for technology that prevents prisoners from making cell phone calls. There is a solution available to rectify this significant problem. API Technologies' signal jamming power amplifiers utilizing LDMOS technology are designed to operate in a band of 1930 to 1990 MHz to jam typical communication band frequencies. These power amps can offer a minimum output power of 100 watts with a gain of 50dB, with multiple carrier inputs. Typical current draw from a nominal +28 VDC supply at rated output power is 8 A. API's designs offer an isolator-protected output to guard against transistor failure due to infinite VSWR mismatch. This jamming renders cell phones inoperable and prevents calls or texts from being sent, rendering the phones essentially useless and mitigating any potential security threats posed by them. Other Applications for Signal Jamming Prisons aren't the only place where cell phone signal jamming is necessary. There are many instances where having access to a cell phone signal could pose a security risk, such as in government buildings, or violate policies, such as in a test taking facility.

Making the Switch from Printed Circuit Boards to Multi-Chip Modules for Deep Well Drilling: Frequently Asked Questions

by Jaymie Murray 2. September 2015 09:50

Traditionally the Oil & Gas industry used Printed Circuit Board (PCB) technology for down well, high-temperature electronics. As demands for higher reliability, longer life and durability in high temperatures in deep well drilling increases, it has been proven that conventional PCBs are no longer a viable solution.  Consequently, the industry is now embracing bare die in multi-chip module solutions (MCMs) in order to fully satisfy these requirements. However, some customers are weary of making the switch to a hybrid solution after relying on PCBs for so long and they often have concerns regarding costs, flexibility, and customisation. Here are a few questions customers frequently ask while contemplating transitioning to a hybrid solution.

Q: How do you justify the cost of switching to hybrids?

A: The transition to hybrid technology is often not driven by cost consideration. There are many reasons for adoption of hybrids:

  • Improved reliability
  • Improved performance – electrical and thermal
  • Significant size reduction
  • Ability to withstand harsh environments, including mechanical shock and vibration, temperature extremes and rapid temperature transitions
  • Improved electrical screening
  • Extended in-service life reduces total life cost

Q: What are the typical lead-times?

A:  There is normally a 20 week design cycle followed by 6 weeks for manufacture.

Q: Can MCM’s be reworked?

A: Rework processes are certified, qualified, and embrace a wide range of capabilities, including:

  • De-lid of module with subsequent hermetic re-lid after repair, and with usual fine and gross leak testing to verify the integrity of the seal
  • Semiconductor die removal and replacement
  • Passive component (resistors, capacitors and inductors) removal and replacement
  • Wire bond replacement
  • Thick film track repair with wire bonds or adhesives
  • Module can be re-sealed and re-tested

Q: How do you hybridise an existing PCB for high temperature operation?

A: There are several steps involved with customising an existing PCB in order to make it suitable for extremely high temperatures:

  • Supply the current BOM & Schematic: API will check bare die availability by taking the list of active components and checking with the OEM manufacturers if the part is available in bare die form required for C&W. API will provide feedback alternatives where necessary and work with you to fill any gaps in the circuit.
  • Define your environmental specification:  These specifications can include storage / operating temperature, shock & vibration requirements. API will check qualification data and confirm we have the required proven packaging techniques for your application, giving you confidence in the robustness of our packaging solution.
  • Define the space envelope: API will then perform an analysis based on your circuit to ensure we can physically fit the electronics in the space provided.
  • Define the package and I/O requirements: How will we mount the electronics in your tool? API designs custom mechanical package concepts that can remove the need for carrier PCBs not suitable for high temperatures.  I/O density is challenging in high temperature applications as often it can only be realised on the smaller of two sides of the package wall. API will review your I/O requirements and limitations and confirm if achievable. 
  • Convert the passives: Solderable termination / low temperature surface mount parts will need changing for high temperature and adhesive attach suitable for incorporation in a hybrid. API can print high temperature thick film resistors and recommend manufacturers with proven reliability.
  • Define your qualification plan: With no industry standards in place, how do you know what is best? API has an independent UKAS test house with experience in high temperature qualification plans, and we are able to review your environmental specifications and assist in defining a qualification plan.
