SAW vs. BAW: How the Delay Line Technologies Stack Up

by Jaymie Murray 8. June 2015 08:11

SAW (Surface Acoustic Wave) and BAW (Bulk Acoustic Wave) technologies are widely used in a variety of applications, including filters, oscillators, transformers, and delay lines. SAW and BAW delay lines in particular offer several advantages over other signal wave technologies and are used in a variety of applications, from Electronic Warfare (EW) target generation to communications systems for television and video. While they are used in somewhat similar applications, SAW and BAW technologies are each unique and have distinctive characteristics. Factors such as required signal delay, frequency, footprint, and cost all must be considered when choosing the best delay line solution for a project. 

Both SAW and BAW devices exploit the piezoelectric effect of certain substrate materials such as quartz and lanthanum gallium silicate by using interdigital transducers (IDTs) to convert acoustic waves to electrical signals and vice versa. Delay lines that utilize SAW and BAW are designed to introduce a calculated delay into the transmission of a wave signal. This signal delay could be needed for a variety of reasons. For example, in weather Doppler systems, weather radars emit pulses which track the movement and location of objects such as hailstones and raindrops. BAW delay lines are used to control the timing of these pulses. SAW delay lines provide required delays to synchronize data in communications systems such as television broadcasting. 

In each of these examples, one technology is the best choice over another because of their respective characteristics. SAW delay lines are usually smaller and lighter than BAW delay lines, which gives them a smaller footprint and therefore can make them less expensive. SAW delay lines also typically offer a wide frequency range from 30 to 2000 MHz. However, SAW delay lines can only provide a fairly small delay range of 0.1 to 10 µsec. If a larger delay range is needed, then BAW delay lines, with a typical range of 0.15 to 3000 µsec, are the best option. This can translate into a larger footprint and raise costs somewhat, but the wider delay range allows for increased adaptability and flexibility.  BAW can also be safely used in a wider temperature range than devices that use SAW, making it a more appropriate choice for harsh or extreme conditions. 

While they are both equally reliable and can offer the delays needed for effective wave signal processing, SAW and BAW each have their own distinct advantages. Ultimately, the best delay line option will be the one that most closely meets important project requirements, such as footprint, frequency, cost, and delay time.

5 Advantages of GaN Solid State Pulsed Power Amplifiers Over TWT Amplifiers

by Jaymie Murray 16. March 2015 10:25

Traveling Wave Tube (TWT) amplifier technology has several inherent limitations that are easily overcome by using the kind of state-of-the-art GaN Solid State Pulsed Power Amplifiers designed and manufactured by API Technologies. The benefits of utilizing GaN transistor technology over TWT include longer lifespan, decreased risk associated with infant mortality after long storage periods, and the elimination of multiple single point failure sources. 

 

5 Advantages of GaN Solid State Pulsed Power Amplifiers Over TWT Amplifiers Your website Remove concern about TWT damage at turn-on after extended storage periods Eliminate a system’s finite life due to cathode exhaustion in the TWT To minimize risk of damage after prolonged storage, an 8-24 hour heater burn-in is recommended before cathode voltage is applied to TWT amplifiers. SSPA amps do not have this risk and can be immediately turned on after extended storage periods. Although there are steps that can be taken to extend cathode life, TWTs still have a finite operating lifetime. By using a GaN SSPA instead, cathode exhaustion can be eliminated altogether, significantly extending the system’s operating life.Get distributed final stage health monitoring & early failure warning while maintaining system operational integrity Eliminate multiple single point failure sources in the TWT SSPA uses parallel combined transistors that provide a soft fail configuration. Parallel power sources in the SSPA provide the opportunity to monitor amplifier health at multiple power stages. TWT relies on energy transfer from the electron beam into the RF signal traveling along a helix wire. All components in the tube are potential single point hard failure sources. Your website Improved reliability meets modern Electronic Warfare (EW) system requirements Because GaN SSPAs are more reliable than TWT amps, they can be used in highly complex modern EW systems. micro.apitech.com/pulsed-power-amplifiers

Delay Lines Week: Why API's Analog Delay Lines Are the Best Choice over Digital

by Allison Goss 13. March 2015 08:58

While many of API's competitors offer digital delay line options, they have several distinct disadvantages compared to API's analog delay lines. Cost, size, and weight can all be significantly lower with analog delay lines, while still offering higher MTBF (Mean Time Before Failure) rates and reliability.

Delay Lines APPLICATIONS API Technologies Where Can You Find API's Delay Lines? API's Delay Lines, featuring BAW (Bulk Acoustic Wave), SAW (Surface Acoustic Wave), Coaxial ­ High Frequency, LC (Lumped Constant), & Steel ­ Pulse Compression topologies, are used in a number of applications. Maritime Radar Doppler Processing Weather radars emit pulses which track the movement and location of objects like raindrops, hailstones, etc. Delay lines are used to control the timing of these pulses. On-board radar scanners provide bearing and distance of ships and land targets in the vicinity for collision avoidance and navigation at sea.EW Target Generation Communications Systems Clock Synchronization A radar target generator passes a radar signal through delay lines to a receiver to simulate a fixed target in time, which may be used to range calibrate the system. In many telecommunications networks, delay lines are used to synchronize information to set clock timing.
