12.6 GHz to 15.4 GHz, GaAs, MMIC, I/Q Downconverter

The ADMV1010 is a compact, gallium arsenide (GaAs) design, monolithic microwave integrated circuit (MMIC), I/Q downconverter in a RoHS compliant package optimized for point to point microwave radio designs that operates in the 12.6 GHz to 15.4 GHz frequency range. The ADMV1010 is optimized to work as a low noise, upper sideband (low side local oscillator (LO)), image reject downconverter.

The ADMV1010 provides 15 dB of conversion gain with 25 dB of image rejection. The ADMV1010 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 LO. IF1 and IF2 mixer outputs are provided, and an external 90° hybrid is needed to select the required sideband. The I/Q mixer topology reduces the need for filtering the unwanted sideband. The ADMV1010 is a much smaller alternative to hybrid style SSB downconverter assemblies, and it eliminates the need for wire bonding by allowing the use of surface-mount manufacturing assemblies.

The ADMV1010 downconverter comes in a compact, thermally enhanced, 4.9 mm × 4.9 mm, 32-terminal LCC package. The ADMV1010 operates over the −40°C to +85°C temperature range.
