General Description
The HMC-ALH445 is a GaAs MMIC HEMT self-biased,
wideband Low Noise Amplifier die which operates
between 18 and 40 GHz. The amplifier provides
9 dB of gain, 3.9 dB noise figure at 28 GHz and
+12 dBm of output power at 1 dB gain compression
while requiring only 45 mA from a single +5V supply.
The HMC-ALH445 amplifier is ideal for integration into
Multi-Chip-Modules (MCMs) due to its small size.
