The ADMV1012 is a compact, gallium arsenide (GaAs) design, monolithic microwave integrated circuit (MMIC) double sideband (DSB) 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 in phase/quadrature (I/Q), double balanced mixer, where a driver amplifier drives the local oscillator (LO) with a ×2 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 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 mm × 4.9 mm, 32-terminal LCC. The ADMV1012 operates over the −40°C to +85°C temperature range.

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
The circuit board used in the application must use RF circuit design techniques. Signal lines must have 50 Ω impedance, and the package ground leads and exposed pad must be connected directly to the ground plane. Use a sufficient number of via holes to connect the top and bottom ground planes. The evaluation circuit board is available from Analog Devices, Inc., upon request.
Tools & Simulations
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
