Overview
The HMC902-SX, manufactured by Analog Devices Inc., is a gallium arsenide (GaAs) pseudomorphic high-electron-mobility transistor (pHEMT) monolithic microwave integrated circuit (MMIC) low noise amplifier (LNA). This device operates within the frequency range of 5 GHz to 11 GHz, making it suitable for various high-frequency applications. The HMC902-SX is self-biased with optional bias control for quiescent drain current (IDQ) reduction, enhancing its flexibility and efficiency.
