HMC311LP3 / 311LP3E
InGaP HBT GAIN BLOCK
MMIC AMPLIFIER, DC - 6 GHz
v04.1108
General Description
Features
Functional Diagram
The HMC311LP3(E) is a GaAs InGaP Heterojunction
Bipolar Transistor (HBT) Gain Block MMIC
SMT DC to 6 GHz ampli ers. This 3x3mm
QFN packaged ampli er can be used as either a
cascadable 50 Ohm gain stage or to drive the LO of
HMC mixers with up to +17 dBm output power. The
HMC311LP3(E) offers 14.5 dB of gain and an output
IP3 of +32 dBm while requiring only 56 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: +32 dBm
Gain: 14.5 dB
50 Ohm I/O’s

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 and exposed paddle should be con-
nected 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.
