Surface Acoustic Wave (SAW) filters are among the most popular types of communication filters for most radio systems due to their high selectivity, low insertion loss and narrow passband characteristics. SAW filters are used in a wide variety of applications including, but not limited to, digital TV receivers, cellular base station receivers, digital mobile phones, and satellite communication to name a few.

The AFS20A20-1227.60-T2 is a SAW filter specifically designed for use in cellular base station receivers. Its primary purpose is to filter unwanted interfering signals, and pass the signal carrying the desired information. This will ensure that the receiver is operating at optimal performance without any interference from outside sources.

The AFS20A20-1227.60-T2 is a low-profile, compact device that is easily integrated into a variety of radio systems. The filter is constructed using a piezoelectric substrate with an internal interdigital transducer (IDT). This IDT is responsible for creating the surface acoustic wave that is used to filter the incoming signal. It operates at a center frequency of 1227.60MHz, has a bandwidth of 70MHz, and offers an insertion loss of less than 2dB.

The working principle of the AFS20A20-1227.60-T2 is simple yet effective. The incoming signals pass through the IDT and are then filtered by the surface acoustic wave created by the piezoelectric substrate. The filter is designed to have high quality factor, which will ensure that the desired signal is passed while suppressing any unwanted interfering signals. This will then be transmitted to receiver for further processing.

Given its low profile, excellent performance, and wide bandwidth, the AFS20A20-1227.60-T2 is an ideal solution for use in cellular base station receivers. The filter is designed to reduce interference, pass the desired signal, and allow the receiver to operate at optimal performance.
