HMC547ALC3TR

RF Switches Overview

The HMC547ALC3TR is a GaAs pHEMT MMIC SPDT switch from Analog Devices Inc., operating from DC to 28.0 GHz in a 16-SMT (3x3) package. It features low insertion loss of 2.4 dB and high isolation of 34 dB typical. The device supports a P1dB of 23 dBm and an IIP3 of 46 dBm at 50 Ohms. Operating temperature ranges from -40°C to +85°C with a maximum supply voltage of 5 V and current consumption of 1 mA.

RF Switches Feature Summary

• High isolation non-reflective topology for signal integrity
• Broadband coverage from DC to 28.0 GHz
• Low power consumption suitable for portable systems
• Leadless ceramic surface mount packaging

RF Switches Applications

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

RF Switches Procurement Notes

Verify the specific suffix LC3 versus ALC3 when sourcing, as availability differs significantly between these variants. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Check for obsolescence notices or PCN documents regarding discontinuation of older LC3 versions.

RF Switches Selection Notes

Select this component for applications requiring wide bandwidth up to 28 GHz with minimal reflection. Ensure the design accommodates the 16-VFQFN bare pad thermal dissipation needs. Compare against HMC547LC3TR if legacy compatibility is required, noting that ALC3 is the currently active general-purpose variant.

RF Switches Part Context

Part of the HMC547 series of broadband SPDT switches. The ALC3 variant serves as the standard general-purpose replacement for the discontinued LC3 version. Both utilize GaAs pHEMT technology for high performance in compact surface-mount packages.

RF Switches Replacement Considerations

HMC547LC3TR is the direct predecessor but is obsolete. HMC547ALC3TR is the active general-purpose equivalent. Verify pinout and electrical specifications match before substitution.
