Functional Diagram
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.
