With a power sources. It offers a lower noise figure compared to an radio frequency (RF) and local oscillator (LO) range of 6 GHz active mixer, ensuring superior dynamic range for high to 26.5 GHz, and an intermediate frequency (IF) bandwidth of performance and precision applications. dc to 5 GHz, the HMC8191 is ideal for applications requiring a The HMC8191 is fabricated on a gallium arsenide (GaAs) metal wide frequency range, excellent RF performance, and a simple semiconductor field effect transistor (MESFET) process and uses design with fewer components and a small printed circuit board Analog Devices, Inc. mixer cells and a 90-degree hybrid. The (PCB) footprint. A single HMC8191 can replace multiple HMC8191 is available in a compact, 4 mm 4 mm, 24-terminal narrow-band mixers in a design. leadless chip carrier (LCC) package and operates over a 40C to The inherent I/Q architecture of the HMC8191 offers excellent +85C temperature range. An evaluation board for the HMC8191 image rejection and thereby eliminates the need for expensive is also available from the Analog Devices website. filtering for unwanted sidebands.
