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.
