Functional Diagram

General Description

The HMC475ST89(E) is a InGaP Heterojunction

Bipolar Transistor (HBT) Gain Block MMIC SMT

ampliﬁer covering DC to 4.5 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 +25 dBm output power.

The HMC475ST89(E) offers 21.5 dB of gain and +35

dBm output IP3 at 850 MHz while requiring only 110

mA from a single positive supply. The Darlington

topology 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= 9.1 Ohm, T_A= +25° C
