Overview
The ADMV1012AEZ from Analog Devices Inc. is a compact, gallium arsenide (GaAs) monolithic microwave integrated circuit (MMIC) designed as an in-phase/quadrature (I/Q) downconverter. This device is optimized for point-to-point microwave radio designs operating within the 17.5 GHz to 24 GHz input frequency range. It features a radio frequency (RF) low noise amplifier (LNA) followed by an I/Q double balanced mixer, with a driver amplifier driving the local oscillator (LO) using a ×2 multiplier. The ADMV1012AEZ is RoHS compliant and comes in a thermally enhanced, 4.9 mm × 4.9 mm, 32-terminal leadless chip carrier (LCC) package.
