YQM1814F

The YQM1814F Series is a compact SAW filter designed to provide an ideal balance between miniature size and RF performance. Housed in a 1.8 × 1.4 mm ceramic SMD package, it supports frequencies from 600 MHz to 2700 MHz and covers major LTE, GNSS, Bluetooth, Wi-Fi, and Sub-GHz communication bands.

Positioned between ultra-miniature and larger package solutions, the YQM1814F offers improved power handling, excellent interference suppression, and reliable performance across consumer, industrial, and automotive applications. It is widely used in smartphones, IoT modules, GNSS receivers, and wireless communication systems.
