Abstract :
A design method for an L-band frequency quadrupler with composite right/left-handed transmission line is proposed. The left-handed transmission line in the proposed frequency quadrupler suppresses the fundamental component (f 0), while the composite right/left-handed lambda/4 open stub reduces unwanted higher-order harmonics. From the experimental results, unwanted harmonics are suppressed to achieve harmonic distortion of 51lambdadBc minimum with output phase noise of lambda94.34lambdadBc/Hz at 10lambdakHz offset.
