Overview
The HMC8402-SX, produced by Analog Devices Inc., is a gallium arsenide (GaAs) pseudomorphic high electron mobility transistor (pHEMT) monolithic microwave integrated circuit (MMIC) low noise amplifier. This device operates across a wide frequency range of 2 GHz to 30 GHz, making it versatile for various high-frequency applications. The amplifier is self-biased, requiring only a single positive supply voltage to achieve a drain current of 68 mA. It is designed to provide high gain, low noise figure, and high output power, making it suitable for demanding microwave and millimeter-wave systems.
