Functional Diagram  
General Description  
The HMC479ST89  
& HMC479ST89E are SiGe  
Heterojunction Bipolar Transistor (HBT) Gain Block  
MMIC SMT amplifiers covering DC to 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 +20 dBm output  
power. The HMC479ST89 offers 15 dB of gain with a  
+33 dBm output IP3 at 850 MHz while requiring only  
75 mA from a single positive supply. The Darlington  
feedback pair used results in reduced sensitivity to  
normal process variations and excellent gain stability  
over temperature while requiring a minimal number of  
external bias components.
