Additional Details:

The TA1120A SAW filter typically exhibits an insertion loss of around 2 to 3 dB and a rejection of 40 dB or higher for frequencies outside the passband. It operates at a center frequency of 1120 MHz with a bandwidth tailored to the specific application. The filter is typically housed in a small surface-mount package, such as a 3x3 mm or 5x5 mm SMD package, which allows for easy integration into printed circuit boards. The operating temperature range typically spans from -40°C to +85°C. The materials used in the SAW filter construction are chosen for their piezoelectric properties and temperature stability, ensuring reliable performance over its operating life. Detailed specifications regarding the filter's performance, including insertion loss, passband ripple, group delay, and impedance matching, can be found in the manufacturer's datasheet. The TA1120A is designed to meet the stringent requirements of modern wireless communication systems, providing excellent filtering performance in a compact and reliable package.
