USD003A Datasheet, PDF (1/2 Pages) CTS Corporation – Band 3 USD Series Duplexer

USD003A - PRELIMINARY
Band 3 USD Series Duplexer
Features
 Low Loss with High Rejection
 Superior power handling and reliability
 Universal footprint across all FDD frequency bands
Applications
 Wireless Infrastructure applications
 High-performance carrier-grade small-cells using linearized
PA for 1.0-2.0W at the antenna port.
 Wide-band pico-cells or small-cells requiring multi-channel
or carrier aggregation.
Part Dimensions: 61.4 × 11.8 × 10.9 mm • 20.8 g
Materials: Ag plated ceramic block with tin plated brass shield
Description
Surface mount ceramic duplexer supports a universal footprint across all FDD frequency bands enabling the use of
a common system PCB. Provides superior rejection, insertion loss, reliability, as well as both peak and average
power handling compared to other duplexer technologies.
