General Description
The HMC481ST89 & HMC481ST89E are SiGe
Heterojunction Bipolar Transistor (HBT) Gain Block
MMIC SMT amplifiers covering DC to 5 GHz. Pack-
aged 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(E) offer 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
