Functional Diagram
General Description
The HMC474SC70(E) is a general purpose SiGe
Heterojunction Bipolar Transistor (HBT) Gain Block
MMIC SMT amplifier covering DC to 6 GHz. This
industry standard SC70 packaged amplifier can be
used as a cascadable 50 Ohm RF/IF gain stage with
up to +8 dBm output power. The HMC474SC70(E)
offers 15 dB of gain with a +20 dBm output IP3 at 850
MHz while requiring only 25 mA from a single positive
supply as low as +3V. 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.
