Functional Diagram

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
