Product Overview

The QPQ1289 is a high performance Bulk Acoustic Wave

(BAW) Duplexer designed for Small Cell applications. It is

specifically designed to address bands 4, 10, and 66. For

band 66, the uplink is fully covered while the downlink is

partially covered with 70 MHz bandwidth.

The QPQ1289 provides low insertion loss and high

rejection making it an ideal choice for Small Cells. This

duplexer is housed in a compact, RoHs compliant

2.00 mm x 2.50 mm x 0.91 mm surface mount package

(SMP).
