ADRF6780 6 GHz to 24 GHz Wideband Upconverter

The ADRF6780 is a silicon germanium (SiGe) design, wideband, microwave upconverter optimized for point to point microwave radio designs operating in the 5.9 GHz to 23.6 GHz frequency range.

The upconverter offers two modes of frequency translation. The device is capable of direct conversion to radio frequency (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 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 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 compact, thermally enhanced, 5 mm × 5 mm LFCSP package. The ADRF6780 operates over the −40°C to +85°C temperature range.
