New techniques for reflector network design in single-ended HEMT RF/microwave frequency multipliers

Microwave and RF frequency multipliers have a wide range of uses in the electronic arena. It has been demonstrated that incorporating reflector networks into the design process can improve the performance of multipliers. This paper presents the development of alternative designs for reflector networks used in the designing of HEMT frequency multipliers. Conversion gains of 6.5 dB for narrowband designs (10% bandwidth) and 1 dB for wideband designs (35% bandwidth) have been attained. The fundamental and third harmonic rejection is approximately 30 dBc for the narrowband designs and 50 dBc for the wideband designs.
