The rat-race coupler performances are ideal to design a V-band six-port-based downconverter using the quasiconventional architecture (with two pairs of antiparallel diodes connected to rat-race quadrature outputs), similar to those presented in [13] for automotive radars, at 77 GHz.
The block diagram of the 2.4/5.7-GHz Weaver-Hartley downconverter is shown in Fig.
A SINGLE RACK UNIT dual-band downconverter permits a user to select any frequency in either C-band (3.4-4.2 GHz) or Ku-band (10.95-12.75 GHz).
A digital downconverter (DDC) provides frequency zooming for signal bandwidths from 40 MHz to as low as a few kHz.
The VSA combines the new NI PXIe-5603 downconverter with the new NI PXIe-5653 local oscillator synthesizer and the NI PXIe-5622, a 150 MS/s intermediate frequency (IF) digitizer.
The region selected for output determines if Mitto acts as an upconverter or downconverter. The filters automatically adjust in accordance with the conversion being performed.
The chip integrates upconverter, downconverter, VCO, synthesizer, IF amplifier, RF gain control and IF gain control.
The 26.5 GHz high performance analog downconverter module offers greater than 170 dB of measurement range with a good noise floor, based on the PSA series spectrum analyzer.
Signals from licensed transmitters outside the 3.7 to 4.2-GHz band, if strong enough, could overload the downconverter and cause picture degradation.
The mixer can be used as an up- or downconverter. The LTC5552 is useful in upconversion applications with its DC-capable differential IF port that enables the LO to be close in frequency to the RE Its low LO to RF leakage of less than -25 dBm eases the burden on the external filter.
