Surface acoustic wave (SAW) filters are widely used in commercial and military applications where precise frequency control is important. They are most commonly used in wireless communication, frequency synthesizers, tuned amplifiers and 24-26GHz radar systems. The B39202B4219U810 SAW filter is a high performance standard product that has been developed for use in a wide variety of applications.

The B39202B4219U810 SAW filter features low insertion loss, high rejection, low dispersion, wide bandwidth, and excellent temperature characteristics. It has a wide passband (34.8-40.85GHz) and offers precise control with QPSK (quadrature phase shift keying) and CPFSK (continuous phase frequency shift keying) modulation schemes. The B39202B4219U810 can be used in applications where high rejection of frequencies outside the passband is required.

The working principle of the B39202B4219U810 SAW filter is based on the principle of acoustic waves. The filter employs a piezoelectric transducer to propagate surface acoustic waves (SAW) at the interface of a piezoelectric layer and a solid substrate. A signal applied to the transducer generates mechanical vibrations on a surface of the substrate, propagating sound waves in opposite directions. The direction of travel of the SAW determines its filter characteristics; the SAW propagating in the same direction as the applied signal is known as the forward SAW (FSW), the SAW propagating in the opposite direction as the applied signal is known as the backward SAW (BSW). The BSW is used to filter signals, rejecting frequencies outside the passband.

The B39202B4219U810 SAW filter is a low power, compact, and cost-effective device, suitable for applications requiring precise frequency control. Its wide passband and excellent temperature characteristics make the B39202B4219U810 ideal for microwave and millimeter wave communication systems such as point-to-point radio, radar, satellite communications and aerospace telemetry. Its low insertion and return loss as well as its high rejection of out-of-band signals make it a popular choice for frequency synthesizers, mobile radio base stations and other wireless communication systems.

In conclusion, the B39202B4219U810 SAW filter is an ideal choice for use in a variety of applications where precise frequency control is required, such as wireless communication, point-to-point radio, radar, satellite communications, frequency synthesizers, tuned amplifiers and 24-26GHz radar systems. The filter features low insertion and return loss as well as excellent temperature characteristics, making it suitable for a number of commercial and military applications.
