Surface Acoustic Wave (SAW) filters are devices used in radio communication systems to select and pass specific frequencies, while blocking unwanted frequencies. The AFS20A05-719.00-T2 filter is a typical SAW filter which uses acoustic waves propagating along the surface of a piezoelectric substrate such as quartz to filter signals.

The device is designed to transmit frequencies within a pass-band of 719.00 MHz and is housed in a miniature package with a 0.5” x 0.5” form factor. The device also offers basic levels of performance over a wide temperature range of -45° to 85°C.

The AFS20A05-719.00-T2 filter is a quartz-based SAW filter specifically designed for use in antenna tuning and filter applications. Its low profile, excellent frequency stability, high Q factor and good power handling capability make it an ideal choice for base stations and mobile radio applications.

The filter\'s frequency response is optimized to eliminate out-of-tune signals and unwanted noise. Its 3-section design offers an additional level of filtering, helping to reject crossover interfering signals. The AFS20A05-719.00-T2 also features a high dielectric temperature stability which helps to ensure that the device\'s output signal does not drift over time.

The device\'s working principle is based on the use of acoustic waves propagating along the surface of a piezoelectric substrate such as quartz. A voltage or current applied to the piezoelectric substrate creates a mechanical vibration which is then converted back into an electrical signal. This vibration is filtered according to the filter\'s specifications and the desired frequency is used to produce the output signal.

The AFS20A05-719.00-T2 SAW filter is designed for use in analog and digital communication applications. It is suitable for use in applications such as cellular base station infrastructure, mobile radio antenna integration, satellite communication system design, Wi-Fi networking, and in-building distributed antenna system (DAS) implementations.

The AFS20A05-719.00-T2 SAW filter offers a valuable solution for filtering signals in high frequency radio communication systems. Its 3-section design and excellent frequency stability makes it an ideal choice for applications where precise frequency control and performance over wide temperature ranges are required. The device is housed in a miniaturized packaging and is designed for use with standard 0.1” pitch, SMD mounting.

In conclusion, the AFS20A05-719.00-T2 SAW filter is a highly reliable solution for high frequency radio communication systems. Its 3-section design offers excellent frequency stability and the device is housed in a miniature package, making it an ideal choice for applications where precise frequency control and performance over wide temperature ranges are required.
