General Description
The HMC772LC4 is a GaAs MMIC HEMT Low Noise
Wideband Amplifier which operates between 2 and
12 GHz. The amplifier provides 15 dB of gain, 1.8 dB
noise figure up to 12 GHz and output IP3 of +25 dBm,
while requiring only 45 mA from a +4V supply voltage.
The Psat output power of up to +15 dBm enables the
LNA to function as a LO driver for many of HIttite’s
balanced, I/Q or image reject mixers. The HMC772LC4
also features I/Os that are DC blocked and internally
matched to 50 Ohms, making it ideal for SMT based
high capacity microwave radio applications. The
HMC772LC4 is housed in a RoHS compliant 4x4 mm
QFN leadless ceramic package.

Description
These pins and ground paddle
must be connected to RF/DC ground.
This pin is AC coupled
and matched to 50 Ohms.
Gate control for amplifier. Please follow “MMIC Amplifier
Biasing Procedure” application note. See application circuit
for required external components.
Power Supply Voltage for the amplifier. See application circuit
for required external components.
The pins are not connected internally; however, all data
shown herein was measured with these pins connected to
RF/DC ground externally.
This pin is AC coupled
and matched to 50 Ohms.
