InGaP HBT ACTIVE BIAS
MMIC AMPLIFIER, 0.05 – 3 GHz
v02.0813
General DescriptionFunctional Diagram
The HMC740ST89E is an InGaP Heterojunction
Bipolar Transistor (HBT) Gain Block MMIC SMT
amplier covering 0.05 to 3 GHz. Packaged in an
industry standard SOT89, the amplier can be used
as a cascadable 50 Ohm RF or IF gain stage as
well as a PA or LO driver with up to +18 dBm output
power. The HMC740ST89E offers 15 dB of gain with
a +40 dBm output IP3 at 100 MHz, and can operate
directly from a +5V supply. The HMC740ST89E
exhibits excellent gain and output power stability over
temperature, while requiring a minimal number of
external bias components.
