The HMC8193 is a passive, in phase/quadrature (I/Q), monolithic microwave integrated circuit (MMIC) mixer that can be used either as an image rejection mixer for receiver operations, or as a single-sideband upconverter for transmitter operations from 2.5 GHz to 8.5 GHz. The inherent I/Q architecture of the HMC8193 offers excellent image rejection and thereby eliminates the need for expensive filtering of unwanted sidebands. The mixer also provides excellent local oscillator (LO) to radio frequency (RF) and LO to intermediate frequency (IF) isolation and reduces the effect of LO leakage to ensure signal integrity.Being the HMC8913 is a passive mixer, it does not require any dc power sources. The device offers a lower noise figure than an active mixer, ensuring superior dynamic range for high performance and precision applications.The HMC8193 is fabricated on a gallium arsenide (GaAs), metal semiconductor field effect transistor (MESFET) process and uses Analog Devices, Inc., mixer cells and a 90° hybrid. It is available in a compact, 4 mm × 4 mm, 24-lead LCC package and operates over the −40°C to +85°C temperature range. An evaluation board for this device is also available.ApplicationsTest and measurement instrumentationMilitary, aerospace, and radarDirect conversion receivers
