B39941B9517P810 Filters

SAW Filters

Surface Acoustic Wave (SAW) filters are key passive elements in today’s mobile communication systems. A typical SAW filter contains an electromechanical transducer, which convert electrical signals to acoustic waves, propagating along the crystal surface with the help of an acoustic mirror. The acoustic waves eventually re-coupled back to the surface, forming an output electrical signal. A SAW filter is therefore able to create a highly selective passband filter with minimal insertion loss.

B39941B9517P810 is a SAW filter designed for packet-based system applications. It is capable of providing a selectivity technique by maintaining an extremely sharp electrical attenuation of >55 dB. It is suitable for many markets, such as Industrial, Medical and Telecommunications. It also tailors the filter characteristics to the customer’s needs with an excellent ability to suppress undesired frequencies.

B39941B9517P810 Application & Working Principle

The B39941B9517P810 is a highly integrated SAW filter that enables packet-based communication systems. It is used in bandwidth applications such as Wi-Fi, Bluetooth and Zigbee wireless standards, cellular communication, satellite navigation, and automotive applications. It is also suitable for noise suppression and signal pre-processing.

The B39941B9517P810 is based on the resonator-type SAW filter. It consists of a quartz crystal substrate and transducer electrodes that convert electrical signals into acoustic waves. The acoustic waves are propagated along the surface of the quartz crystal. The output is then re-coupled to obtain a highly selective passband with minimal insertion loss. The filter is optimally designed to maintain a high level of rejection (exceeding 55 dB), thus preventing unwanted signals from interfering with the desired signals.

The B39941B9517P810 SAW filter has a wide operating temperature range of -20°C to 85°C, making it ideal for extreme temperature conditions. It also has a high-performing package design that protects the device from mechanical and environmental shocks. It is a small, lightweight component, making it suitable for compact designs.

The B39941B9517P810 SAW filter also has excellent power handling capability. It is able to operate at 25 dBm peak input power (50 Ω). It also employs excellent rejection characteristics, making it ideal for suppressing spurious signals.

Conclusion

The B39941B9517P810 SAW filter is a highly integrated device which offers superior performance for various wireless communication applications. It is suitable for industrial, medical and telecommunications markets, and can be customised to individual requirements. It is a small, light weight component which can operate over a wide temperature range and is capable of withstanding harsh environmental conditions. It is capable of providing an impressive selectivity technique and offers outstanding rejection characteristics, making it an ideal choice for suppressing spurious signals.
