Analog Devices ADMV10x Converters
Analog Devices’ ADMV10x Converters use I/Q mixer topology to reduce the need for unwanted sideband filtering. Part of a series of RF up/down converters, the monolithic microwave integrated circuits (MMIC) are manufactured using gallium arsenide (GaAs) and offer designers a high-performance product in a small, convenient package for a variety of audio and video data transmission applications.
The series consists of the ADMV1009, the ADMV1010, the ADMV1011 and the ADMV1012. The ADMV1009 is a single sideband (SSB) I/Q upconverter optimised for point-to-point microwave radio designs that operate in the 12.7 to 15.4 GHz frequency range. The device provides 21 dB of conversion gain with 20 dB of image rejection, and its upconversion requires only a 180° balun to select the required sideband.
The comparable SSB I/Q downconverter for the ADMV1009 is the ADMV1010, which is optimised for the 12.6 to 15.4 GHz frequency range. The device provides 15 dB of conversion gain with 25 dB of image rejection, and its downconversion requires a 90° hybrid to select the required sideband. The ADMV1009 and ADMV1010 serve as a smaller alternative to hybrid-style SSB upconverter and downconverter assemblies, respectively.
The ADMV1011 upconverter features the same conversion gain and image rejection as the ADMV1009 but outputs across a higher frequency range of 17 to 24 GHz. It is also fully integrated, needing only a 90° hybrid to select the required sideband. Its downconverter counterpart is the ADMV1012, which operates in the 17.5 to 24 GHz input frequency range and provides 15 dB of conversion gain, 25 dB of image rejection and a 2.5 dB noise figure. Both devices function as a smaller alternative to hybrid-style DSB assemblies, each eliminating the need for wire bonding by allowing the use of surface-mount manufacturing assemblies.
The converters are available in a compact, thermally enhanced 4.9 x 4.9 mm LCC package. They are suitable for RF applications such as satellite communications, radar, electronic warfare systems and point-to-point radios.
