HMC311SC70E

Overview

The HMC311SC70E is an InGaP HBT Gain Block MMIC amplifier from Analog Devices Inc., designed for surface-mount applications. It operates across a frequency range of 0 Hz to 8 GHz, providing a typical gain of 15 dB with a noise figure of 5 dB. The device requires a 5 V supply and draws approximately 55 mA to 74 mA of current. Key performance metrics include a P1dB compression point of 11 dBm to 15 dBm and an OIP3 of 30 dBm. Packaged in a compact SC-70-6 case, it supports operation between -40°C and +85°C.
