HMC8191 is a passive wideband I/Q MMIC mixer that can be used either as an image reject mixer for receiver operations or as single sideband upconverter for transmitter operations. With RF and LO range of 6 GHz to 26.5 GHz, and IF bandwidth of dc to 5 GHz, HMC8191 is ideal for applications requiring wide frequency range, excellent RF performance and a simpler design with fewer parts and a smaller PCB footprint. A single HMC8191 can replace multiple narrowband mixers in a design.
The inherent I/Q architecture of HMC8191 allows it to offer excellent image rejection and thereby eliminate the need for expensive filtering for unwanted sidebands. The mixer also provides excellent LO-RF and LO-IF isolation and reduces the effect of LO leakage to ensure signal integrity.
