ADRF6780

Data Sheet 5.9 GHz to 23.6 GHz, Wideband, Microwave Upconverter ADRF6780 FEATURES GENERAL DESCRIPTION Wideband RF output frequency range: 5.9 GHz to 23.6 GHz Two upconversion modes Direct conversion from baseband I/Q to RF Single sideband upconversion from real IF LO input frequency range: 5.4 GHz to 14 GHz LO doubler for up to 28 GHz Matched 100 Ω balanced RF output, LO input, and IF input High impedance baseband inputs Sideband suppression and carrier feedthrough optimization Variable attenuator and power detector for Tx power control Programmable via 4-wire SPI interface 32-lead, 5 mm × 5 mm LFCSP microwave packaging APPLICATIONS Point to point microwave radios Radar, electronic warfare systems Instrumentation, automatic test equipment (ATE) 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....
