HMC451LC3TR

Overview

The HMC451LC3TR is a GaAs PHEMT MMIC medium power amplifier manufactured by Analog Devices Inc. It operates within a frequency range of 5 GHz to 20 GHz and provides a typical gain of 17 dB. The device requires a single 5 V supply with a current consumption of 114 mA. Key performance metrics include a noise figure of 7 dB, a 1 dB compression point (P1dB) of 19.5 dBm, and an output third-order intercept point (OIP3) of 32 dBm. It is housed in a leadless 16-SMT surface-mount package.

Feature Summary

• Utilizes GaAs PHEMT technology for efficient medium power amplification
• Operates across a wide 5 GHz to 20 GHz frequency spectrum
• Features a leadless RoHS-compliant SMT package for compact integration

Applications

• GPS receiver front-ends
• Point-to-point microwave radio links
• Satellite communication systems
• Electronic warfare applications

Procurement Notes

Verify the specific suffix 'TR' indicates reel packaging when sourcing components. Confirm that the manufacturer is Analog Devices Inc., as part numbers may be distributed through various authorized channels. Ensure compatibility with 5 V supply requirements and check for moisture sensitivity level (MSL 3) handling precautions during assembly. Cross-reference datasheet revisions to ensure parameter consistency.

Selection Notes

Select this component for designs requiring high linearity and moderate power output in the K-band and above. Consider the 19.5 dBm P1dB and 32 dBm OIP3 for signal integrity needs. Evaluate the 114 mA current draw against system power budgets. The 16-SMT package size suits space-constrained PCB layouts compared to larger ceramic packages.

Part Context

This model belongs to the HMC451 series of RF amplifiers from Analog Devices. It is the tape-and-reel variant of the HMC451LC3. The series is designed for general-purpose RF amplification tasks where broadband performance and efficiency are critical. It complements other MMICs in the Analog Devices portfolio for complete signal chain solutions.
