Overview
The HMC397 die, produced by Analog Devices Inc., is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) Gain Block MMIC amplifier. This device operates from DC to 10 GHz and is designed for use as either a cascadable 50 Ohm gain stage or to drive the Local Oscillator (LO) of HMC mixers. It offers 15 dB of gain and an output IP3 of +32 dBm, while requiring only 56 mA from a +5V supply. The amplifier features a Darlington feedback pair, which reduces sensitivity to normal process variations and ensures excellent gain stability over temperature. Its small size (0.22mm²) makes it ideal for integration into Multi-Chip-Modules (MCMs).
