YQM5050F

The YQM5050F Series is a high-performance SAW bandpass filter housed in a 5.0 × 5.0 mm ceramic SMD package. Designed for demanding RF applications, it supports frequencies from 76.5 MHz to 1000 MHz and covers VHF/UHF communications, Sub-GHz ISM bands, GNSS systems, and intermediate-frequency (IF) receiver applications.

Featuring a larger cavity structure than conventional 3030 and 3838 packages, the YQM5050F delivers higher power handling capability, stronger interference immunity, and superior out-of-band rejection. It is an ideal filtering solution for professional wireless communications, industrial IoT networks, automotive electronics, and high-reliability RF systems.
