Overview
The HMC405 is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) Gain Block MMIC amplifier produced by Analog Devices Inc. This amplifier operates from DC to 10 GHz and is designed for use in various high-frequency applications. It can be utilized as either a cascadable 50 Ohm gain stage or to drive the Local Oscillator (LO) of HMC mixers with up to +17 dBm output power. The HMC405 is known for its stable gain over temperature and minimal external bias components, making it an excellent choice for integration into Multi-Chip-Modules (MCMs) due to its small size of 0.38 x 0.58 x 0.1 mm.
