GENERAL DESCRIPTION

The ADRF6780S-CSL is a silicon germanium (SiGe) design, wi-

deband, microwave upconverter optimized for point to point micro-

wave radio designs operating in the 5.9 GHz to 23.6 GHz frequency

range.

The upconverter offers two modes of frequency translation. The de-

vice is capable of direct conversion to RF from baseband in-phase

quadrature (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 gen-

erally 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 suppress-

ing 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 allows powering down the output power detector to reduce

power consumption when power monitoring is not necessary.

The ADRF6780S-CSL upconverter comes in a compact, thermally

enhanced, 5 mm × 5 mm LFCSP. The ADRF6780S-CSL operates

over the −40°C to +85°C temperature range.
