ABSTRACT:
A microwave frequency divider operable in 2-16 GHZ range over octave bandwidths. A circuit resonant at a subharmonic frequency is formed by a pair of input microstrip transmission lines coupled to a pair of output microstrip transmission lines. Each input line is terminated by a varactor diode. The input signal is supplied to the resonant circuit by a pair of microstrip lines functioning as a two stage quarter wave transformer. A pair of slots are formed in the ground plane underneath the resonant circuit. The electric field distortion thereby produced serves to bias the varactors into forward conduction for efficient subharmonic generation.
