Overview
The HMC526LC4 is a compact general-purpose I/Q MMIC (Monolithic Microwave Integrated Circuit) mixer produced by Analog Devices Inc. This component is designed to operate within the frequency range of 6 to 10 GHz and can be used as either an Image Reject Mixer or a Single Sideband Upconverter. It is fabricated in a GaAs MESFET process and features two standard Hittite double-balanced mixer cells along with a 90-degree hybrid. The mixer is packaged in a leadless, RoHS-compliant SMT (Surface Mount Technology) package, making it a smaller alternative to traditional hybrid style mixers and upconverters.
