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.
