Abstract :
High-efficiency bipolar microwave frequency multipliers with wideband performance, high conversion gain, and good spectral properties have been developed. Experimental conversion gains of up to 7 dB have been attained for narrowband designs ( approximately=12% BW) and greater than 0 dB for wideband designs (>or=40%) at C-band. Corresponding fundamental and third-harmonic rejections are greater than 45 dBc and 30 dBc, respectively. Extensive modeling and computer-oriented design utilizing harmonic balance have been employed.<>
