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

Evaluation PCB
The circuit board used in the nal application should
use RF circuit design techniques. Signal lines
should have 50 Ohm impedance while the package
ground leads should be connected directly to the
ground plane similar to that shown. A sufficient
number of via holes should be used to connect
the top and bottom ground planes. The evaluation
board should be mounted to an appropriate heat
sink. The evaluation circuit board shown is available
from Hittite upon request.
