HMC347ALP3ETR

RF Switches Overview

The HMC347ALP3ETR is a GaAs MMIC SPDT non-reflective switch from Analog Devices Inc., operating from DC to 14 GHz. It features low insertion loss and high isolation, suitable for VSAT applications. The component utilizes a 16-QFN (3x3 mm) surface-mount package. Key electrical specifications include an insertion loss of approximately 0.8 dB and isolation of 38 dB at 14 GHz. It operates on a single 5 V supply with a typical current consumption of 25 mA.

RF Switches Feature Summary

• Non-reflective SPDT architecture ensures signal integrity across the frequency band.
• GaAs MMIC technology supports wideband operation up to 14 GHz.
• Compact 16-QFN package facilitates dense PCB layout integration.

RF Switches Applications

• VSAT satellite communication systems
• Point-to-point microwave radio links
• Test and measurement instrumentation

RF Switches Procurement Notes

Verify the specific suffix 'ETR' indicates tape-and-reel packaging configuration distinct from the 'E' variant. Confirm RoHS compliance status through official documentation as manufacturing processes may vary. Ensure the source document explicitly lists this part number to avoid confusion with similar HMC347 series components.

RF Switches Selection Notes

Select this component when non-reflective switching behavior is critical for system stability in high-frequency environments. The GaAs process offers superior performance compared to silicon alternatives in the 14 GHz range. Evaluate power handling requirements against the datasheet limits before implementation in RF signal paths.
