USB255A - PRELIMINARY

2535-2575 MHz USB Series TDD Bandpass Filter

Features

. Subset of Band 41 for China Unicom

. Low Loss with High Rejection

. Low ripple

. Universal footprint across family for all TDD bands

Applications

Part Dimensions: 25.9 × 8.9 × 6.7 mm • 3.7 g

Materials: Ag plated ceramic block with tin plated brass shield

. Wireless Infrastructure applications

. High-performance carrier-grade TDD basestations for up

to 5.0W at the antenna port.

Description

Surface mount ceramic bandpass filter supports a universal footprint across all TDD 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 bandpass filter technologies.
