HMC772LC4 v01.0709 Amplifiers - Low Noise - SMT 7 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* Parameter Min. Frequency Range Gain Typ.

Signal lines should have 50 Ohm impedance while the package ground leads and exposed paddle 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.
