HMC441LP3TR

RF Amplifiers Overview

The HMC441LP3TR is a GaAs PHEMT MMIC medium power amplifier designed for broadband operation from 6 GHz to 18 GHz. It features a typical gain of 17 dB and a saturated output power of +20 dBm with 27% PAE. The device operates on a single +5V supply voltage, optionally requiring gate bias. It includes integrated input and output matching for 50 Ohm systems. The component is housed in a compact 16-lead QFN surface-mount package measuring 3x3 mm.

RF Amplifiers Feature Summary

• Broadband frequency coverage spanning 6 GHz to 18 GHz
• High saturated output power capability at +20 dBm
• Integrated 50 Ohm input and output impedance matching
• Single positive supply voltage operation

RF Amplifiers Applications

• VSAT communication systems
• Point-to-point radio links
• Military electronic warfare applications
• Local oscillator drivers for mixers

RF Amplifiers Procurement Notes

Verify the specific suffix 'LP3TR' to confirm the 16-QFN package and 6-18 GHz frequency range, distinguishing it from other variants like the LM1 or LP3 which have different specifications. Ensure RoHS compliance status matches current manufacturing standards. Confirm that the supplier provides original manufacturer documentation to validate authenticity and traceability.

RF Amplifiers Selection Notes

Select this component when a wide bandwidth covering C through K bands is required in a minimal footprint. It is suitable for designs needing high output power without complex external matching networks due to integrated 50 Ohm interfaces. Consider the single-supply requirement for simplified biasing circuits compared to multi-voltage alternatives.

RF Amplifiers Part Context

This part belongs to the Hittite (now Analog Devices) HMC441 family of GaAs PHEMT MMICs. While sharing similar technology, variants differ significantly in frequency range and package type. The LP3TR variant specifically targets higher frequencies up to 18 GHz in a small QFN form factor, distinct from lower-frequency or larger-package siblings.

RF Amplifiers Replacement Considerations

Direct substitutes include HMC441LP3 (non-tray version) or HMC441LM1 if the frequency range can be adjusted to 7-15.5 GHz. Verify pinout compatibility and thermal performance when swapping between QFN and LCC packages.
