Overview
The HMC311SC70ETR from Analog Devices Inc. is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) Gain Block MMIC amplifier designed for operation from DC to 8 GHz. This amplifier is packaged in an industry-standard SC70 package, making it suitable for a variety of applications requiring high gain and low noise. The HMC311SC70ETR can be used as either a cascadable 50 Ohm gain stage or to drive the LO port of HMC mixers with up to +15 dBm output power. It offers 15 dB of gain and an output IP3 of +30 dBm, while requiring only 54 mA from a +5V supply.
