HMC641LC4TR-R5

RF Switches Overview

The HMC641LC4TR-R5 is a broadband non-reflective Single-Pole Quad-Throw (SP4T) RF switch manufactured by Analog Devices Inc. It utilizes GaAs pHEMT technology and is housed in a compact 24-lead QFN package measuring 4x4 mm. The device operates from DC to 20 GHz with a 50 Ohm impedance. Key electrical specifications include an insertion loss of 2.3 dB, isolation of 40 dB, a P1dB of 25 dBm, and an IIP3 of 41 dBm. It supports surface mount installation and functions within a temperature range of -40°C to 85°C.

RF Switches Feature Summary

• Broadband operation covering DC to 20 GHz frequencies
• Non-reflective SP4T topology for signal routing
• High linearity performance with 41 dBm IIP3
• Compact 4x4 mm ceramic QFN package

RF Switches Applications

• VSAT communication systems
• Test and measurement equipment
• Wireless infrastructure components

RF Switches Procurement Notes

Verify the specific suffix 'R5' against official Analog Devices documentation to confirm reel packaging configuration. Ensure compatibility with the 24-QFN footprint during PCB layout. Confirm current lifecycle status as distribution channels may list varying availability or end-of-life notices for this component series.

RF Switches Selection Notes

Select this component when high-frequency broadband switching up to 20 GHz is required. The non-reflective design minimizes signal reflection issues compared to reflective switches. Consider the 24-QFN package size for space-constrained designs requiring robust GaAs performance at microwave frequencies.

RF Switches Part Context

This part belongs to the HMC641 series of RF switches from Analog Devices. It is functionally related to variants such as HMC641LC4 and HMC641ALC4TR, which share similar core switching capabilities but may differ in package type or manufacturing process revisions. The LC4 designation typically indicates a specific ceramic package variant within the product family.

RF Switches Replacement Considerations

HMC641LC4 and HMC641ALC4TR are documented functional equivalents within the same series. Verify pinout and thermal pad requirements before substitution.
