HMC311SC70 / 311SC70E
v04.0814
InGaP HBT GAIN BLOCK
MMIC AMPLIFIER, DC - 8 GHz
General Description
Features
Functional Diagram
The HMC311SC70(E) is a GaAs InGaP Heterojunction
Bipolar Transistor (HBT) Gain Block MMIC SMT
DC to 8 GHz amplier. Packaged in an industry
standard SC70, the amplier can be used as either
a cascadable 50 Ohm gain stage or to drive the LO
port of HMC mixers with up to +15 dBm output power.
The HMC311SC70(E) offers 15 dB of gain and an
output IP3 of +30 dBm while requiring only 54 mA
from a +5V supply. The Darlington topology 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 dBm
Output IP3: +30 dBm
Gain: 15 dB
Cascadable, 50 Ohm I/O’s
Single Supply: +5V
Industry Standard SC70 Package
