HMC478ST89 / 478ST89E
SiGe HBT GAIN BLOCK
MMIC AMPLIFIER, DC - 4 GHz
v05.0710
General Description
Functional Diagram
The
HMC478ST89
&
HMC478ST89E
are
SiGe
Heterojunction Bipolar Transistor (HBT) Gain Block
MMIC SMT amplifiers covering DC to 4 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 +20 dBm
output power. The HMC478ST89(E) offers 22 dB of
gain with a +30 dBm output IP3 at 850 MHz while
requiring only 62mA 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.
P1dB Output Power: +18 dBm
Gain: 22 dB
Output IP3: +30 dBm
Cascadable 50 Ohm I/Os
Single Supply: +5V to +8V
Industry Standard SOT89 Package
Robust 1,000V ESD, Class 1C
Included in the HMC-DK001 Designer’s Kit
Typical Applications
