General Description
The HMC479ST89 is a SiGe Heterojunction Bipolar
Transistor (HBT) Gain Block MMIC SMT ampli鏗乪r
covering DC to 5 GHz. Packaged in an industry
standard SOT89, the ampli鏗乪r 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.
