Surface acoustic wave (SAW) filters are an essential component of Radio Frequency (RF) and wireless communication systems. They provide high level of selectivity and excellent frequency stability, and can be customized to meet specific communication system requirements. SAW filters have a wide range of applications, including mobile, two-way radio, satellite communication, and digital data communication systems. The B39881B9861P810W99 is a type of SAW filter that is designed to have precise cut-off frequencies with excellent frequency stability and high ripple/transmission loss. It is suitable for a variety of applications including low and medium frequency RF applications.

The B39881B9861P810W99 is constructed using piezoelectric quartz crystal substrates and electrodes that are deposited and patterned onto the crystal surface. When an alternating electrical signal is applied to the input port of the filter, the signal induces surface acoustic waves along the crystal surface which travel away from the input port. The surface acoustic waves cause the crystal to vibrate, resulting in surface acoustic wave propagation.

The surface acoustic wave produces a waveguide-like effect along the surface of the crystal, as the crystals are patterned with interdigital transducers that allow transmission and reflection of surface acoustic waves. By the interdigitated transducers, frequency selectivity is introduced into the SAW filter, resulting in higher ripple and transmission loss at the desired cut-off frequency and excellent frequency stability. The SAW filter is designed to transmit signals in the range of 5 MHz to 8 MHz up to 30 dB, with insertion loss up to 2 dB. The B39881B9861P810W99 has a maximum operating temperature of 85°C.

The B39881B9861P810W99 is suitable for a variety of applications, including mobile communications, two-way radio, satellite communications, digital data communication systems, frequency hopping systems, and spread spectrum systems. It is used in applications such as bandpass, notch, stopband and duplexer filters, which all require precise cut-off frequencies with excellent frequency stability and high ripple and transmission loss. It is also used in RF surveillance systems, GPS systems, and satellite receivers. In addition, this SAW filter is used in computer networks, speech processing systems, and signal processing systems.

In summary, the B39881B9861P810W99 is a type of SAW filter that is designed to provide precise cut-off frequencies with excellent frequency stability and high ripple/transmission loss. It has a wide range of applications, including mobile communications, two-way radio, satellite communications, digital data communication systems, frequency hopping systems, signal processing systems, and RF surveillance systems. The B39881B9861P810W99 is designed to transmit signals in the range of 5 MHz to 8 MHz up to 30 dB, with insertion loss up to 2 dB.
