General Descriꢀtion
The HMC751LC4 is a high dynamic range GaAs
pHEMT MMIC Low Noise Amplifier (LNA) housed in
a leadless “Pb free” RoHS compliant SMT package.
The HMC751LC4 provides 25 dB of small signal
gain, 2.2 dB of noise figure and output IP3 of +25 dBm.
The P1dB output power of +13 dBm also enables the
LNA to function as a LO driver for balanced, I/Q or
image reject mixers. The HMC751LC4 allows the use
of surface mount manufacturing techniques.
