Introduction

The ADMV1012 is a compact, gallium arsenide (GaAs) design, monolithic microwave integrated circuit (MMIC), in phase/quadrature (I/Q) downconverter in a RoHS compliant package optimized for point to point microwave radio designs that operate in the 17.5 GHz to 24 GHz input frequency range. The ADMV1012 provides 15 dB of conversion gain with 25 dB of image rejection, and 2.5 dB noise figure. The ADMV1012 uses a radio frequency (RF) low noise amplifier (LNA) followed by an I/Q, double balanced mixer, where a driver amplifier drives the local oscillator (LO) with a x2 multiplier. IF1 and IF2 mixer quadrature outputs are provided, and an external 90° hybrid is required to select the required sideband. The I/Q mixer topology reduces the need for filtering of unwanted sideband. The ADMV1012 is a much smaller alternative to hybrid style, double sideband (DSB) downconverter assemblies and eliminates the need for wire bonding by allowing the use of surface-mount manufacturing assemblies. The ADMV1012 downconverter comes in a compact, thermally enhanced, 4.9 mmx4.9 mm, 32-terminal LCC. The ADMV1012 operates over the -40℃ to +85℃ temperature range.
