The ADMV1014 is a SiGe, microwave downconverter accepts an input RF frequency of 24 GHz to 44 GHz and downconverts it to an IF frequency from 0.8 to 6 GHz. The downconverter has two modes of frequency translation - Direct conversion from RF to baseband I/Q and Image rejecting downconversion to complex IF. It provides a signal conversion gain of more than 12.5 dB with 52 dBc of image rejection. The ADMV1014 has a flexible local oscillator (LO) system, including a frequency quadruple option allowing up to a 41 GHz range of LO input frequencies to cover a radio frequency (RF) input range as wide as 24 GHz to 44 GHz. A square law power detector is provided to allow monitoring of the power levels at the mixer inputs. The detector output provides closed-loop control of the RF input variable attenuator through an external op amp error integrator circuit option.
The ADMV1014 downconverter is available in a compact, thermally enhanced, 5 x 5 mm LGA package and is ideal for point-to-point microwave radios, radar and electronic warfare system applications. It operates over the -40°C to +85°C case temperature range.
