ADI's ADRF6780 is a silicon germanium (SiGe) design, wideband, microwave upconverter optimized for point-to-point microwave radio, radar, and ATE designs operating in the 5.9 GHz to 23.6 GHz frequency range. It offers two upconverter modes, direction conversion from baseband IQ to radio frequency (RF) and single sideband upconversion from real infrared frequency (IF), making it ideal for high precision applications.

The device has baseband inputs which are high impedance and are generally terminated off chip with 100 Ω differential back terminations. The baseband I/Q input path can be disabled and a modulated real IF signal anywhere from 0.8 GHz to 3.5 GHz can be fed into the IF input path and upconverted to 5.9 GHz to 23.6 GHz while suppressing the unwanted sideband by typically better than 25 dBc. The serial port interface (SPI) allows tweaking of the quadrature phase adjustment to allow optimum sideband suppression. In addition, the SPI interface allows powering down the output power detector to reduce power consumption when power monitoring is not necessary. The ADRF6780 upconverter comes in a small thermally enhanced, 5 mm x 5 mm LFCSP package
