Overview
The HMC903 is a gallium arsenide (GaAs), pseudomorphic high electron mobility transistor (pHEMT), monolithic microwave integrated circuit (MMIC), low noise amplifier (LNA) produced by Analog Devices Inc. This amplifier is self-biased with an optional bias control for reducing the quiescent drain current (IDQ). It operates within the frequency range of 6 GHz to 18 GHz, making it suitable for various high-frequency applications. The HMC903 is housed in a 16-lead, 3 mm × 3 mm, LFCSP package and is RoHS compliant.
