Overview
The HMC462A, produced by Analog Devices Inc., is a GaAs MMIC pHEMT Low Noise Distributed Amplifier. It operates over a wide frequency range of 2 to 20 GHz, making it suitable for various high-frequency applications. The amplifier is self-biased, requiring a single +5V supply at 63 mA, and is internally matched to 50 Ohms for both input and output, facilitating easy integration into Multi-Chip-Modules (MCMs).
