SAW Filters

Surface acoustic wave (SAW) filters are filters for very high frequencies, from several hundred megahertz to several gigahertz. A specific type of filter, the B39438X6964D100, is one of many SAW filters. This particular filter is intended for use in wireless applications.

Application field

The B39438X6964D100 is suitable for radio frequency (RF) and wireless communications systems. It is widely used in a variety of applications, including cell phones, broadcasting, digital TV, radio transmitters, receivers, satellite communication systems, microwave systems, transceivers, and more. It is also used in medical devices and other specialized sectors that require high frequency precision.

Working principle

The B39438X6964D100 consists of two transducers: an IDT (Interdigitated Transducer) and a reflector. The IDT converts an electrical signal into a acoustic wave which travels across the filter. When the wave reaches the reflector, it is returned in the opposite direction, until it ultimately reaches the other side of the IDT again, where it is converted back into an electrical signal. The duration of travel for the acoustic wave and its return is determined by the physical characteristics of the filter, which sets the cut-off frequency. This determines the range of frequencies which are allowed to pass through the filter. The B39438X6964D100 is a high frequency filter that operates from a frequency range of 800 MHz to 2700 MHz.

Advantages

The B39438X6964D100 is relatively small and low-cost, allowing it to be used in many applications. It is also extremely reliable and durable, capable of withstanding high temperatures and electrical surges. It is also relatively easy to install, and requires no additional components. The filter is also very precise in terms of frequency selection, with a cut-off frequency accuracy of +/- 0.3dB across the specified frequency range.
