LFB321G64SN4-761

Overview

The Murata LFB321G64SN4-761 is a ceramic bandpass filter designed for surface-mount applications. It features a center frequency of 1.64 GHz and a bandwidth of 37.5 MHz. The component operates within a temperature range of -40°C to +85°C and supports a maximum power capacity of 1W. Housed in a 1210 (3225 metric) package measuring 3.20mm x 2.50mm, it utilizes the SN series construction.

Feature Summary

• Provides selective signal filtering with a defined center frequency and bandwidth
• Supports high-power handling capabilities up to 1W
• Constructed using robust ceramic materials for stable RF performance

Applications

• Wireless communication systems requiring specific frequency selection
• RF front-end modules in mobile devices
• Base station equipment operating in the 1.64 GHz range

Procurement Notes

Verify the exact center frequency and bandwidth specifications against the official datasheet before integration. Confirm that the 1210 package dimensions align with the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check for RoHS compliance status if required by regional regulations.

Selection Notes

Select this component when a fixed center frequency of 1.64 GHz is required. Consider the 1W power rating for high-signal environments. Evaluate the 37.5 MHz bandwidth against system noise requirements. Compare physical size constraints with alternative packages like the standard 1206 or larger formats if space permits.

Part Context

This part belongs to Murata's LFB series of ceramic filters. These components are engineered for RF applications where compact size and reliable performance are critical. The SN suffix indicates specific packaging or testing variations within the series. They serve as alternatives to discrete LC filters in modern miniaturized electronics.

Replacement Considerations

Direct substitutes must match the 1.64 GHz center frequency and 1210 footprint. Verify bandwidth compatibility to ensure signal integrity is maintained. Cross-reference insertion loss characteristics with the original design requirements.
