5.9 GHz to 23.6 GHz, Wideband, Microwave Upconverter Data Sheet ADRF6780 FEATURES GENERAL DESCRIPTION Wideband RF output frequency range: 5.9 GHz to 23.6 GHz The ADRF6780 is a silicon germanium (SiGe) design, wideband, Two upconversion modes microwave upconverter optimized for point to point microwave Direct conversion from baseband I/Q to RF radio designs operating in the 5.9 GHz to 23.6 GHz frequency Single sideband upconversion from real IF range. LO input frequency range: 5.4 GHz to 14 GHz The upconverter offers two modes of frequency translation. The LO doubler for up to 28 GHz device is capable of direct conversion to radio frequency (RF) Matched 100 balanced RF output, LO input, and IF input from baseband I/Q input signals, as well as single sideband (SSB) High impedance baseband inputs upconversion from a real intermediate frequency (IF) input Sideband suppression and carrier feedthrough optimization carrier frequency. The baseband inputs are high impedance and Variable attenuator and power detector for Tx power control are generally terminated off chip with 100 differential back Programmable via 4-wire SPI interface terminations. The baseband I/Q input path can be disabled and 32-lead, 5 mm 5 mm LFCSP microwave packaging a modulated real IF signal anywhere from 0.8 GHz to 3.5 GHz can APPLICATIONS 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 Point to point microwave radios 25 dBc. The serial port interface (SPI) allows tweaking of the Radar, electronic warfare systems quadrature phase adjustment to allow optimum sideband Instrumentation, automatic test equipment (ATE) 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 40C to +85C temperature range.
