Overview
The HMC751LC4 is a high dynamic range GaAs pHEMT MMIC Low Noise Amplifier (LNA) produced by Analog Devices Inc. It is housed in a leadless, Pb-free, RoHS compliant SMT package. This amplifier is designed to operate within the frequency range of 17 to 27 GHz, making it suitable for various high-frequency applications. The HMC751LC4 offers 25 dB of small signal gain, a noise figure of 2.2 dB, and an output IP3 of +25 dBm. It is also capable of delivering a P1dB output power of +13 dBm, which enables it to function as a LO driver for balanced, I/Q, or image reject mixers. The component supports surface mount manufacturing techniques, enhancing its usability in modern electronic designs.
