Overview
The HMC594LC3B is a GaAs pHEMT MMIC Low Noise Amplifier (LNA) designed by Analog Devices, Inc. This amplifier operates within the frequency range of 2 to 4 GHz, making it ideal for various high-frequency applications. It is characterized by its extremely flat performance characteristics, including a small signal gain of 10 dB, a noise figure of 3 dB, and an output IP3 of +36 dBm across the operating band. The compact 3x3 mm SMT package and DC blocked RF I/Os make it suitable for test & measurement equipment, military assemblies, and other space-constrained applications.
