FREQUENCY CONVERTER UNITS FOR KU- TO KA-BAND OPERATION.
Abstract
An unbalanced ridge waveguide converter was developed for the high Ku-band which satisfied the project requirements for conversion loss and VSWR when equipped with a single diode. In order to satisfy the project specifications for power level and spurious signals, a balanced converter using two diodes was fabricated and tested. The balanced converter should cancel the local oscillator and its harmonics, and the even harmonics of the input signal at the output. Tests show that a high order of mechanical symmetry is required for good balance. To satisfy the power requirement with only two diodes it was necessary to use the contractors. This change in diodes resulted in a generally inferior performance. For the low Ku-band converter, an X-band converter previously developed was modified and tested. VSWR's at Ku and Ka-band are almost satisfactory. Balance properties appear to be acceptable. No conversion experiments have been performed. (Author)
