General Description
Functional Diagram
The HMC-ALH244 is a two stage GaAs MMIC HEMT
Low Noise Amplifier die which operates between
24 and 40 GHz. The amplifier provides 12 dB of gain,
a noise figure of 3.5 dB, and requires only 45 mA
from a +4V supply voltage. The HMC-ALH244 amplifier
die is ideal for integration into Multi-Chip-Modules
(MCMs) due to its small size (3.5 mmꢀ).
