SAW Filters: B39232B8338P810S5 Application Field and Working Principle

SAW (Surface Acoustic Wave) Filters are an electronic component used to regulate through frequency selectivity. It is designed to match an incoming frequency and block undesired frequencies. The SAW filter is highly effective in a variety of wireless applications, such as RFID, automotive systems, and mobile communications.A SAW filter has two main components: a base transducer and an acoustic reflector. The transmitted signals are then reflected off of the formers back along the opposite path, making the formers a resonating cavity. A SAW filter can be designed to pass or cut off a specific frequency.The B39232B8338P810S5 is a specific SAW filter made by EPCOS AG. It is specially designed to reduce out-of-band interference and pass through a specific frequency range with very low loss. It has a compact size and low power consumption.The B39232B8338P810S5 is ideal for automotive applications. It uses EPCOS AG\'s B39733 process, which has excellent temperature stability. It is also capable of blocking wideband interference while allowing signals within its passband frequencies. This makes it ideal for use in vehicular installed systems and communication networks.The B39232B8338P810S5 has a working frequency of 800-2180 MHz and a nominal passband of 810 MHz. Its passband insertion loss is 0.2dB across the entire band, and its out-of-band rejection is excellent for automotive applications. The filter features a low power consumption rate with high isolation and low group delay ripple.The B39232B8338P810S5 is also designed for use in ISM band applications. It has an excellent passband loss of 0.55dB and can be used in applications like WFP, WLAN and Zigbee. The filter\'s wide operating temperature (−30 to +85° C) and high stability make it a reliable choice for ISM applications.The working principle of the B39232B8338P810S5 is based on an acoustic resonator, which is a mechanical resonant structure that generates resonance frequencies. The mechanical structure is composed of a transducer and reflector, which are connected via a crystal sheet. The SAW filter allows signals in the passband frequency to pass through with minimal loss, while signals outside the passband frequency range are blocked. The filter works by creating an acoustic wave that reflects off of the reflector and is sent back through the transducer. This creates a resonant cavity, which only allows signals of a certain frequency to pass. The size and shape of the resonator determines the frequency of the signal that passes through the filter.The B39232B8338P810S5 is a highly versatile SAW filter that is most suitable for automotive applications and ISM applications. Its excellent temperature stability and high out-of-band rejection make it a reliable solution for a variety of wireless applications. The filter has a low power consumption rate and excellent passband insertion loss, making it ideal for use in vehicular communication networks.
