Abstract : A detailed description of the computer program for the electrical parameters of coupled and uncoupled microstrip transmission lines is presented. Experimental data are also given on a trial 10-dB directional coupler designed from data obtained from the computer program. The design, fabrication, and loss characteristics of thin-film CdS longitudinal-mode transducers are described. Input admittance data for these transducers are presented. These data are used to deduce values for the transducer capacitance, thickness coupling factor, and series resistance. Design techniques for upper-sideband up-converters with wide (10:1) tuning ranges are discussed. An up-converter has been built and tested that operates from 200 to 2000 MHz with an instantaneous bandwidth of 35 MHz. Effects of the lower sideband are identified and accounted for in the design.
