Features
P1dB Output Power: +17 dBm
The HMC478SC70(E) is a SiGe Heterojunction
Bipolar Transistor (HBT) Gain Block MMIC SMT
amplifier covering DC to 4 GHz. This industry stan-
dard SC70 packaged amplifier can be used as a cas-
cadable 50 Ohm RF/IF gain stage as well as a LO
or PA driver with up to +17 dBm output power. The
HMC478SC70(E) offers 23 dB of gain with a +31 dBm
output IP3 at 850 MHz while requiring only 62 mA
from a single positive supply. The Darlington topol-
ogy results in reduced sensitivity to normal process
variations and excellent gain stability over tempera-
ture while requiring a minimal number of external bias
components.
