RF1211C

Overview

The RF1211C is a Surface Acoustic Wave (SAW) filter manufactured by Murata Electronics, designed for signal conditioning applications. It operates at a center frequency of 315 MHz with a narrowband configuration suitable for receiver front ends. The component features an insertion loss of 2 dB and utilizes an SMD5050-8P package for board mounting. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Narrowband SAW filter architecture optimized for receiver front-end signal conditioning
• Low insertion loss performance for efficient signal transmission
• Compact surface-mount design facilitating integration in space-constrained circuits

Applications

• Receiver front-end filtering in wireless communication systems
• Signal conditioning for 315 MHz ISM band applications
• RF module input stage filtering

Procurement Notes

Verify the specific datasheet version and pinout configuration before integration, as manufacturing revisions may occur. Confirm that the SMD5050-8P footprint matches your PCB layout requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer's official documentation for any updates on end-of-life status or recommended alternative components.

Selection Notes

Select this component when a narrowband filter is required specifically at 315 MHz. The low insertion loss makes it suitable for sensitive receiver chains. Consider the physical dimensions of the SMD5050-8P package during layout planning. Verify compatibility with the target RF circuit impedance and bandwidth requirements against the official electrical characteristics.
