RF1284

Overview

The Murata RF1284 is a Surface Acoustic Wave (SAW) filter designed for wireless radio frequency applications. It operates with a center frequency of 319.508 MHz and provides a bandwidth of 600 kHz to 800 kHz, depending on the specific datasheet reference. The component features an insertion loss of approximately 2 dB and supports a voltage rating of 30 V. It is housed in a TO-205AD or TO-39-3 metal can package with through-hole termination. The minimum operating temperature is specified at -40°C.

Feature Summary

• Surface Acoustic Wave technology for effective signal conditioning
• Metal can construction for durability and shielding
• Through-hole mounting capability for robust integration

Applications

• Narrowband receiver front ends
• Wireless communication systems
• Signal conditioning circuits

Procurement Notes

Verify the exact bandwidth specification (600 kHz vs 800 kHz) against the latest official Murata datasheet, as sources vary. Confirm the package designation matches your PCB layout requirements, specifically between TO-205AD and TO-39-3 variants. Ensure the supplier provides RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a narrowband SAW filter is required for the 319.508 MHz range. Consider the through-hole package constraints and metal can size (0.370 inch diameter). Evaluate the 2 dB insertion loss against system sensitivity requirements. Verify thermal performance limits relative to the -40°C minimum operating temperature.

Part Context

This part belongs to Murata's SAW filter portfolio, which includes components for various wireless frequencies. These filters are engineered to isolate specific frequency bands while attenuating out-of-band interference. The RF1284 serves as a specialized solution for legacy or specific industrial wireless protocols requiring precise frequency selection.
