Typical Applications
This HMC-ALH311 is ideal for:
• Point-to-Point Radios
• Point-to-Multi-Point Radios
• Military & Space
• Test Instrumentation
The HMC-ALH311 is a GaAs MMIC HEMT Low Noise
Driver Ampli er die which operates between 22 and
26.5 GHz. The ampli er provides 25 dB of gain, a
typical noise gure of 3 dB at 25 GHz, and +12 dBm of
output power at 1 dB gain compression while requiring
only 52 mA from a +2.5V supply voltage. The HMC-
ALH311 is ideal for microwave radio driver ampli er
applications between 22 to 26.5 GHz. Due to its small
size, the HMC-ALH311 die is ideal for integration into
Multi-Chip-Modules (MCMs).
