SF1188C

Overview

The Murata SF1188C is a Surface Acoustic Wave (SAW) filter designed for signal conditioning in wireless access applications. It operates at a center frequency of 465.0 MHz with a bandwidth of 4 MHz. The device features an insertion loss of 2 dB and utilizes an 8-SMD, no-lead package measuring 5.00 mm x 5.00 mm.

Feature Summary

• Surface Acoustic Wave technology for precise RF filtering
• Optimized for wireless access signal conditioning
• Compact surface-mount design

Applications

• Wireless access systems
• RF signal conditioning circuits
