v02.0514 AMPLIFIERS -LOW NOISE -SMT GaAs HEMT MMIC LOW NOISE
AMPLIFIER, 2 -12 GHz
Typical Applications Features This HMC772LC4 is ideal for: Noise Figure: 1.8 dB • Wideband Communication Systems Gain: 15 dB • Surveillance Systems Output IP3: +25 dBm • Point-to-Point Radios P1dB Output Power: +13 dBm • Point-to-Multi-Point Radios 50 Ohm Matched Input/Output • Military & Space Supply Voltage: +4V @ 45 mA • Test Instrumentation 24 Lead Ceramic 4x4mm SMT Package: 16mm² 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. Electrical Specifications, TA = +25° C, Vdd= +4V, Idd = 45 mA*
