HMC442LC3B

Overview

The HMC442LC3B is a GaAs PHEMT MMIC medium power amplifier designed for surface-mount applications. It operates within the frequency range of 17.5 GHz to 25.5 GHz. Key electrical specifications include a gain of 13 dB, a 1 dB compression point (P1dB) of 22 dBm, and a noise figure of 9 dB. The device requires a supply voltage of 5 V and draws a supply current of 84 mA. It is housed in a leadless, RoHS-compliant 12-VFQFN package with dimensions of 3x3 mm.

Feature Summary

• Utilizes GaAs PHEMT technology for efficient medium power amplification
• Operates across the 17.5 GHz to 25.5 GHz frequency spectrum
• Housed in a leadless, Pb-free SMT package compliant with RoHS standards

Applications

• Point-to-point radio links
• Satellite communication systems
• Electronic warfare equipment

Procurement Notes

Verify the specific suffix (e.g., LC3B vs. TR) to ensure correct packaging and tape-and-reel configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Ensure the evaluation board compatibility if initial prototyping is required.

Selection Notes

Select this component when a medium power output is required in the K/Ka-band range. Consider the 13 dB gain and 22 dBm P1dB for link budget calculations. Evaluate the 9 dB noise figure against system sensitivity requirements. The 5 V supply voltage and 84 mA current draw must be accommodated by the power management design. The 12-pin QFN package dictates specific PCB footprint and thermal dissipation strategies.

Part Context

This component belongs to the HMC442G series of RF amplifiers from Analog Devices. It is part of a family of GaAs MMICs designed for high-frequency wireless applications. The HMC442LC3B serves as a specific variant optimized for medium power output in the 17.5-25.5 GHz band, distinct from lower or higher power variants in the same product line.
