A breadboard, single sideband generator to be used as a homodyne common channel local oscillator covering 7 to 11 GHz was developed and laboratory tested. In addition, an investigation of problems involved in designing wideband, multichannel, homodyne receiving systems for high-precision direction finders that use either phase or amplitude-comparison techniques was conducted. Equations for SNR and signal-to-noise optimization were derived and the effects of VSWR and mixer performance on channel gain tracking were analyzed. Equations for evaluating these effects were also derived. Author
