HMC476SC70TR

Overview

The HMC476SC70TR is a SiGe Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifier from Analog Devices Inc. It operates within a frequency range of DC to 6 GHz. The device provides a typical gain of 19 dB with a noise figure of 2.5 dB. It features a 1 dB compression point (P1dB) of 12 dBm and an output third-order intercept point (OIP3) of 24 dBm. Powered by a 5 V supply, it draws 35 mA of current. The component is housed in a compact SC-70-6 package and supports an input return loss of 20 dB. It functions as a single-channel amplifier suitable for RF applications.
