HMC594
v01.0312
GaAs pHEMT MMIC LOW NOISE
AMPLIFIER, 2 - 4 GHz
General Description
Features
Functional Diagram
The HMC594 is a GaAs PHEMT MMIC Low Noise
Amplier (LNA) chip which operates from 2 to 4 GHz.
The HMC594 features extremely at performance
characteristics including 10 dB of small signal gain,
2.6 dB of noise gure and output IP3 of +36 dBm
across the operating band. This versatile LNA is ideal
for hybrid and MCM assemblies due to its compact
size, consistent output power and DC blocked RF
I/O’s. All data is measured with the chip in a 50 Ohm
test xture connected via one 0.025 mm (1 mil) dia-
meter bondwire of minimal length 0.31 mm (12 mil).
Gain Flatness: ±0.2 dB
Noise Figure: 2.6 dB
Gain: 10 dB
