B39321B3711U410

Surface acoustic wave (SAW) filters are electronic devices which are used to filter out signals at a certain frequency when active components are not viable solutions. The B39321B3711U410 is a SAW filter which has applications in television, satellite and radio receiver systems. It consists of a quartz crystal located between two interdigital transducers (IDT) that convert electrical signals into surface acoustic waves. The B39321B3711U410 is a bandpass filter which offers improved control of the signal’s passband through the use of in-line equalizers.

The B39321B3711U410 features a small geometry which gives it excellent sensitivities to radio frequency and temperature variations. This makes the B39321B3711U410 a compact, reliable, and low-jitter filter for applications where phase noise and spurious responses must be kept as low as possible. It also has a very low insertion loss due to its high Q factor.

The B39321B3711U410\'s working principle is based on the two IDTs which are connected to an electric field along two opposite axes. The IDTs have interdigital electrodes which serve as transducers which emit and receive surface acoustic waves when an electrical signal is applied. These waves travel in opposite directions along the axes and are reflected off a stop having a through-hole, which forces the acoustic wave back outward. The acoustic wave is then picked up by the other IDT acting as a receiver, and an electrical signal is created when the acoustic wave passes through the IDT.

The signal is then filtered through the B39321B3711U410\'s passband. The passband is defined by the IDT frequency response, and any frequency outside the passband is rejected. In addition, the in-line equalizers can be used to further refine the passband characteristics.

The B39321B3711U410 can be used in applications such as radio receivers, satellite receivers, and televisions. It is a reliable and low-jitter filter which provides improved control of the signal passband and is also immune to noise interference. This makes the B39321B3711U410 an ideal choice for applications where phase noise and spurious responses must be kept as low as possible.
