Overview
The HMC129LC4 is a general-purpose, double-balanced monolithic microwave integrated circuit (MMIC) mixer produced by Analog Devices Inc. It is housed in a leadless, Pb-free, RoHS-compliant SMT package. This mixer is designed to operate within the 4 GHz to 8 GHz frequency band and can be used as either an upconverter or a downconverter. It is particularly suited for applications requiring small size, no DC bias, and consistent IC performance.
The HMC129LC4 eliminates the need for wire bonding, allowing for the use of surface mount manufacturing techniques. It performs well as a biphase modulator or demodulator and operates over a wide LO drive input range of +9 to +15 dBm.
