The QPQ1298 bulk acoustic wave (BAW) filter from Qorvo is now being shipped by distributor Mouser Electronics, Inc.

This high-performance BAW 5G filter designed for sub-Band n41 uplink and downlink in base station infrastructure, small cell, and repeater applications.

The filter features low insertion loss and high attenuation, vital for coexistence of 5G cellular bands and Wi-Fi operation in high-data-capacity rural, suburban, and dense urban areas.

It offers single-input and single-output operation in the 160 MHz bandwidth, with frequency ranges from 2515 MHz to 2675 MHz, to address n41 design challenges with bandwidth and Wi-Fi rejection, with no external matching required.

A three-pin 2.00 mm × 1.60 mm × 0.73 mm SMT package also provides engineers with a small-form-factor solution to simplify assembly.

Also available from Mouser is the QPQ1298EVB evaluation board, which features a pre-mounted QPQ1298 filter along with two 50Ω SMA connectors for RF in and RF out.

The evaluation board provides an example application circuit, allowing rapid prototyping when incorporated into existing designs.
