Overview
The HMC405-SX, 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, making it versatile for various high-frequency applications. It can be used 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. The HMC405-SX is designed to provide high gain stability over temperature and requires a minimal number of external bias components due to its Darlington feedback pair design.
