Functional Diagram
General Description
The HMC476SC70(E) is a SiGe Heterojunction Bipolar
Transistor (HBT) Gain Block MMIC SMT amplifiers
covering DC to 6 GHz. This industry standard SC70
packaged amplifier can be used as a cascadable 50
Ohm RF/IF gain stage as well as a LO or PA driver with
up to +12 dBm output power. The HMC476SC70(E)
offers 20 dB of gain with a +24 dBm output IP3 at 850
MHz while requiring only 35 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= 5V, Rbias= 56 Ohm, TA = +25° C
