InGaP HBT Gain Block Amplifier SMT, DC - 4.5 GHz

The HMC475ST89(E) is a InGaP Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifier covering DC to 4.5 GHz. Packaged in an industry standard SOT89, the amplifier can be used as a cascadable 50 Ohm RF/IF gain stage as well as a LO or PA driver with up to +25 dBm output power.

The HMC475ST89(E) offers 21.5 dB of gain and +35 dBm output IP3 at 850 MHz while requiring only 110 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.
