HMC318MS8GE

Overview

The HMC318MS8GE is a surface-mount variable gain low noise amplifier (VGLNA) manufactured by Analog Devices Inc. using GaAs technology. It operates within the 5 GHz to 6 GHz frequency range, providing 9 dB of gain with a typical noise figure of 2.5 dB. The device requires a 3 V supply voltage and draws 6 mA of current. Key performance metrics include a P1dB compression point of 2 dBm, an OIP3 of 13 dBm, and an input return loss of 12 dB. Power dissipation is rated at 634 mW. It functions as a single-channel amplifier suitable for C-band applications.
