Surface Acoustic Wave (SAW) filters are widely used in a number of applications, due to their superior performance and design versatility. The AFS869.0W01-TS4 (3K/REEL) is a general-purpose low-pass filter from the AFS8 series of SAW filters developed by Avago Technologies. This SAW filter is designed to provide excellent performance with low insertion loss, high selectivity and out-of-band rejection. It has a center frequency of 869.0MHz, with an operating bandwidth of 3kHz, and a maximum input power of 10dBm.

The AFS869.0W01-TS4 (3K/REEL) is a low-pass SAW filter, meaning that it allows signals with a frequency lower than the center frequency to pass, while rejecting signals with higher frequency. As such, it can be used to prevent unwanted signals outside the operating bandwidth from entering the circuit. It is designed with a passband of 5 MHz to 864.0 MHz, with a typical insertion loss of 2.0 dB and a typical stopband rejection of over 40 dB.

The AFS869.0W01-TS4 (3K/REEL) is designed for use in communications systems, where high linearity is required to prevent signal distortion. Common application fields for this SAW filter include base stations, cell phones, GPS systems, and Wi-Fi communications. Its wide operating temperature range of -30°C to +85°C enables it to be used in both indoor and outdoor applications.

The AFS869.0W01-TS4 (3K/REEL) is a piezoelectric device, operating on the principle of coupling energy between electrical and mechanical fields. This process is known as electromechanical coupling. The filter contains two electrodes, a dielectric material, and a piezoelectric material. The electrodes transmit and receive electrical signals, while the piezoelectric material vibrates to generate a surface acoustic wave. When the electrical signal crosses the two electrodes, it is converted to an acoustic wave which travels through the piezoelectric material. The acoustic wave is then detected by the receiving electrode and converted back into an electrical signal.

The AFS869.0W01-TS4 (3K/REEL) is a cost-effective, high-performance SAW filter, providing superior signal isolation and linearity. It is easy to integrate into existing circuits or systems, with its compact DIP form factor. Its high resistance to EMI and RFI noise makes it an ideal choice for use in sensitive applications. With its wide operating temperature range and low power consumption, this SAW filter is a versatile solution for a variety of communication system applications.
