Diodes (RTDs) as non-liner elements in sub-harmonic millimetre and sub-millimetre wave mixing circuits. The primary intention of this research work was to evaluate a topology for a sub-harmonic down conversion mixer exploiting the fourth harmonic of a LO signal.
Designs were evaluated by simulation at GHz and GHz with the aim of. For a millimetre wave mixer diode, this might be a quartz substrate embedded in a waveguide channel , . If measurements can confirm the predicted results, everything is fine and the diodes are working properly.
However, more often than not, a measurement of a millimetre wave device. Measurement results give SSB receiver noise temperatures of K at GHz, with an image rejection from dB to 23 dB over the entire band.
