The ADUD-R-0004 from Abracon is a LTCC Surface Acoustic Wave (SAW) Duplexer that operates from 746-756 MHz and 777-787 MHz. It has an insertion loss of less than 2.5 dB (Tx) and 2.3 dB (Rx), and provides more than 55 dB of isolation. This duplexer can handle an input power (CW) of up to 29 dBm (~0.8 W) and provides 23 to 45 dB of rejection above the passband. It has been designed for use in radio frequency (RF) circuits to allow simultaneous transmission and reception of signals through a common antenna.
This RoHS-compliant SAW duplexer provides high isolation between the antenna to Rx and Tx to antenna path with low insertion loss. It is available in a surface-mount package that measures 1.8 x 1.4 x 0.5 mm and is ideal for wireless infrastructure, military, aerospace, test instrumentation, T/R modules, 5G wireless communications, research and development, cellular base stations, and radar applications.
