General Description
The HMC481ST89 is a SiGe Heterojunction Bipolar
Transistor (HBT) Gain Block MMIC SMT amplifier
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 +21 dBm output power.
The HMC481ST89 offers 20 dB of gain with a +33
dBm output IP3 at 1 GHz while requiring only 79
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.
Electrical Specifications, Vs= 8.0 V, Rbias= 39 Ohm, T_A = +25° C
