General Description
The HMC478SC70(E) is a SiGe Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifier covering DC to 4 GHz. This industry standard SC70 packaged amplifier can be used as a cascadable 50 Ohm RF/IF gain stage as well as a LO or PA driver with up to +17 dBm output power. The HMC478SC70(E) offers 23 dB of gain with a +31 dBm output IP3 at 850 MHz while requiring only 62 mA from a single positive supply. The Darlington topology results in reduced sensitivity to normal process variations and excellent gain stability over temperature while requiring a minimal number of external bias components.
