HMC-ALH444 1–12GHz Wideband Low Noise Amplifier Die
Manufacturer: Analog Devices / Hittite Microwave
Product Type: GaAs HEMT MMIC Low Noise Amplifier
Frequency Range: 1GHz to 12GHzPackage: Bare Die
Description: 1–12GHz wideband GaAs HEMT MMIC low noise amplifier die with 17dB typical gain, low noise figure and +19dBm P1dB for communication, surveillance, VSAT, military and test systems.
The HMC-ALH444 is a GaAs HEMT MMIC low noise amplifier die designed for wideband RF and microwave receiver systems operating from 1GHz to 12GHz. It combines low noise, useful gain and driver-level output power in a compact die format for integration into hybrid circuits and multichip modules.
Its broad bandwidth allows one amplifier to cover several communication, radar, surveillance and test bands. HMC-ALH444 is suitable for receiver front ends, intermediate gain stages and local oscillator driver applications where low noise and wide frequency coverage are required.

Typical Applications
Wideband Communication Systems
HMC-ALH444 can be used in broadband RF receivers and communication modules covering multiple microwave bands. It is suitable for designs that require wide frequency coverage without using several narrowband amplifier stages.
Surveillance and Receiver Front Ends
The low-noise design supports surveillance receivers and spectrum-monitoring equipment where weak RF signals must be amplified before filtering, frequency conversion or digital processing.
Point-to-Point and Point-to-Multipoint Radio
The amplifier can be integrated into microwave radio receiver chains, intermediate gain stages and local oscillator paths for point-to-point and point-to-multipoint communication systems.
VSAT and Satellite Communication
HMC-ALH444 is suitable for VSAT terminals and satellite communication equipment requiring a compact broadband amplifier die for receiver or signal-distribution functions.
Military and Space Systems
The die format supports integration into compact microwave assemblies used in radar, electronic surveillance, electronic warfare and other high-reliability RF systems. Qualification and screening requirements must be confirmed separately for each program.
Test and Measurement Equipment
Its broad operating range makes HMC-ALH444 useful in signal analyzers, broadband receivers, microwave test fixtures and general-purpose laboratory RF equipment.
