HMC441LP3TR

Overview

The HMC441LP3TR is a GaAs PHEMT MMIC medium power amplifier from Analog Devices Inc., designed for broadband applications. It operates within a frequency range of 6 to 18 GHz, with specific variants covering 6.5-13.5 GHz or 7-15.5 GHz bands. The device provides a typical gain of 15.5 dB and features a saturated output power (Psat) of +20 dBm at 20% Power Added Efficiency (PAE). Key electrical parameters include a noise figure of 4.5 dB, a 1 dB compression point (P1dB) of 20 dBm, and a third-order intercept point (OIP3) of 32 dBm. It requires a single 5 V supply voltage and draws approximately 90 mA of current.

Feature Summary

• Utilizes GaAs PHEMT technology for high-performance RF amplification in a compact surface-mount package.
• Provides broadband operation suitable for wideband communication systems across multiple gigahertz ranges.
• Delivers medium output power capabilities with high linearity metrics for signal integrity.

Applications

• VSAT (Very Small Aperture Terminal) uplink and downlink amplifiers
• Point-to-point microwave radio links
• Electronic warfare and radar subsystems

Procurement Notes

Verify the exact suffix designation (e.g., LP3 vs. LH5) against the official datasheet to ensure correct frequency coverage and pinout compatibility. Confirm RoHS compliance status as indicated in the specific product documentation. Check for restricted availability or limited stock conditions directly with authorized distributors, as supply constraints may apply to this component series.

Selection Notes

Select this component when a broadband medium-power amplifier is required for frequencies between 6 GHz and 18 GHz. Ensure the design accommodates the 5 V supply requirement and 90 mA bias current. Verify that the QFN package dimensions fit the PCB layout constraints. Consider thermal management requirements due to the power dissipation characteristics at maximum output levels.

Part Context

This part belongs to the HMC441G family of GaAs PHEMT MMICs from Analog Devices. These amplifiers are engineered for robust performance in demanding RF environments. The family includes various packages and frequency-specific variants to support diverse wireless infrastructure needs. The HMC441LP3TR specifically denotes the tape-and-reel packaging format for automated assembly.

Replacement Considerations

Direct substitutes include other parts within the HMC441 family, such as HMC441LC3B (evaluation board context) or HMC441LH5TR, depending on the specific frequency band and package preference. Verify pin compatibility and electrical specifications before substitution.
