Surface Acoustic Wave (SAW) filters are used in numerous telecom related applications. They have been found to provide excellent filtering characteristics at high frequencies. The AFS20A15-2017.50-T2 is a SAW filter designed for use in a high performance, high frequency applications. In this article, we will discuss the application field and working principle of the AFS20A15-2017.50-T2 SAW filter.

SAW filters are used in a variety of telecommunication applications including mobile phones, RFID systems, cordless phones, satellite communications systems and high speed optical networking systems. The AFS20A15-2017.50-T2 is a high performance, high frequency SAW filter specifically designed for applications in the industrial, medical and aviation communications fields. It is also suitable for testing and diagnostics in laboratory environments.

The AFS20A15-2017.50-T2 SAW filter can operate in a wide range of temperatures from -40°C to +85°C. It is designed to be used with a frequency range from 0.2 to 2000MHz. The AFS20A15-2017.50-T2 SAW filter has an insertion loss of 0.9dB and a rejection of more than 40dB. It is built using two interdigital transducers (IDTs). The IDT structure consists of multiple fingers placed close together to form an array of electrodes. Each IDT is placed on a glass substrate and connected to a board.

The working principle of the AFS20A15-2017.50-T2 SAW filter involves the IDTs. When an RF signal is applied to the IDT, it generates sound waves which travel along the surface of the glass substrate. The sound waves reflect off the edge of the substrate and interfere with each other when they meet. This produces a waveform with a specific frequency response. This frequency response can be tuned by changing the length of the IDTs.

The AFS20A15-2017.50-T2 SAW filter is designed to deliver consistent performance in harsh environments characterized by high humidity, vibration, and temperature. It is also designed to provide good attenuation, low insertion loss, and low distortion. The AFS20A15-2017.50-T2 SAW filter is a reliable and robust solution for various industrial, medical, and aviation communication applications.

In conclusion, the AFS20A15-2017.50-T2 SAW filter is a high performance, high frequency filter designed for use in a variety of telecommunication applications. Its working principle involves the use of interdigital transducers, which generate sound waves that travel along the surface of the glass substrate. These sound waves interfere with each other when they meet to form a waveform with a specific frequency response. The AFS20A15-2017.50-T2 SAW filter is designed to deliver consistent performance in harsh environments and provide excellent attenuation, low insertion loss, and low distortion. It is a reliable and robust solution for various industrial, medical, and aviation communication applications.
