General Description

The HMC594 is a GaAs PHEMT MMIC Low Noise Amplifi er (LNA) chip which operates from 2 to 4 GHz. The HMC594 features extremely fl at performance characteristics including 10 dB of small signal gain, 2.6 dB of noise fi 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 fi xture connected via one 0.025 mm (1 mil) diameter bondwire of minimal length 0.31 mm (12 mil).
