Overview
The HMC8192LGTR, produced by Analog Devices Inc., is a passive, wideband, in-phase/quadrature (I/Q) monolithic microwave integrated circuit (MMIC) mixer. This component is designed for use in both receiver and transmitter operations, serving as either an image rejection mixer or a single-sideband upconverter. It operates over a wide frequency range of 20 GHz to 42 GHz for the radio frequency (RF) and local oscillator (LO), and has an intermediate frequency (IF) bandwidth of dc to 5 GHz. This makes it ideal for applications requiring a broad frequency range, excellent RF performance, and a compact design with a small printed circuit board (PCB) footprint.
