The ADRF6780S is a silicon germanium (SiGe) design, wideband, microwave upconverter optimized for point to point microwave radio designs operating in the 5.9GHz to 23.6GHz frequency range.

The upconverter offers two modes of frequency translation. The device is capable of direct conversion to RF from baseband I/Q input signals, as well as single sideband (SSB) upconversion from a real intermediate frequency (IF) input carrier frequency. The baseband inputs are high impedance and are generally terminated off chip with 100Ω differential back terminations. The baseband I/Q input path can be disabled and a modulated real IF signal anywhere from 0.8GHz to 3.5GHz can fed into the IF input path and upconverted to 5.9GHz to 23.6GHz while suppressing the unwanted sideband by typically better than 25dBc. The serial port interface (SPI) allows tweaking of the quadrature phase adjustment to allow optimum sideband suppression. In addition, the SPI allows powering down the output power detector to reduce power consumption when power monitoring is not necessary.

The ADRF6780S upconverter comes in a compact, thermally enhanced, 5mm × 5mm LFCSP. The ADRF6780S operates over the −40°C to +85°C temperature range.
