USD7185A - PRELIMINARY

Band 71 (with B85 UL) USD Series Duplexer

Features

▪ Low Loss with High Rejection

▪ Superior power handling and reliability

▪ Universal footprint across all FDD frequency bands

Applications

ESTIMATE

▪ Wireless Infrastructure applications

Part Dimensions: 63.0 × 16.4 × 10.5 mm • 40.5 g

Materials: Ag plated ceramic block with tin plated brass shield

▪ 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.

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.
