Paper Abstract

The performance of receivers incorporating subharmonically pumped mixers is presented over the signal frequency (RF) range of 585 GHz to 2.1 THz. The mixers employ whisker contacted Schottky barrier diodes in corner cubes. Free standing resonant metal mesh bandpass filters are used to suppress fundamental mode mixing by blocking signals at fLo ± fw while allowing second harmonic mixing by passing radiation at 2fLo ± ff. The spectral performance of the mesh filters is presented and fabrication techniques are briefly discussed. Comparisons are made to similar fundamental mode mixers.
