Abstract :
A report is presented on harmonic mixing results of FIR frequencies with a waveguide-optical harmonic mixer using a micrometer-size Schottky-barrier diode which is able to generate high-order harmonics at room temperature. The frequency measured of the 170.6-μm wavelength line of a methyl alcohol laser is 1757.529±0.005 GHz. It is shown that the micrometer-size Schottky-barrier diode mixer´s efficiency appears to be decreasing as f-4 rolloff in this frequency region, but can be extrapolated to higher frequencies
