General Description
Features
Functional Diagram
The HMC311ST89(E) is a GaAs InGaP Heterojunc-
tion Bipolar Transistor (HBT) Gain Block MMIC SMT
DC to 6 GHz ampli er. Packaged in an industry
standard SOT89, the ampli er can be used as either
a cascadable 50 Ohm gain stage or to drive the LO of
HMC mixers with up to +16.5 dBm output power. The
HMC311ST89(E) offers 16 dB of gain and an output
IP3 of +31.5 dBm while requiring only 54 mA from a
+5V supply. The Darlington feedback pair used results
in reduced sensitivity to normal process variations
and yields excellent gain stability over temperature
while requiring a minimal number of external bias
components.
P1dB Output Power: +15.5 dBm
Output IP3: +31.5 dBm
