Overview
The HMC395-SX from Analog Devices Inc. is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) Gain Block MMIC amplifier, operating from DC to 4 GHz. This amplifier die is designed to serve as either a cascadable 50 Ohm gain stage or to drive the Local Oscillator (LO) of HMC mixers, offering up to +17 dBm output power. It features a gain of 16 dB and an output third-order intercept point (IP3) of +31 dBm, while requiring only 54 mA from a +5V supply. The use of a Darlington feedback pair ensures excellent gain stability over temperature and minimizes the need for external bias components. Its small size of 0.22 mm² makes it ideal for integration into Multi-Chip-Modules (MCMs).
