HMC-ALH445 v03.0410 GaAs HEMT MMIC LOW NOISE AMPLIFIER, 18 - 40 GHz 1 Typical Applications Features This HMC-ALH445 is ideal for: Noise Figure: 3.9 dB 28 GHz Wideband Communication Systems Gain: 9 dB Point-to-Point Radios P1dB Output Power: +12 dBm 28 GHz Point-to-Multi-Point Radios Supply Voltage: +5V 45 mA Military & Space Die Size: 1.6 x 1.6 x 0.1 mm Test Instrumentation General Description Functional Diagram The HMC-ALH445 is a GaAs MMIC HEMT self-biased, wideband Low Noise Ampl ifier die which operates between 18 and 40 GHz. The ampl ifier provides 9 dB of gain, 3.9 dB noise fi gure 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 ampl ifier is ideal for integration into Multi-Chip-Modules (MCMs) due to its small size. Electrical Specifi cations*, T = +25 C, Vdd= +5V A Parameter Min. Typ. Max. Min. Typ. Max.
