Abstract

The analysis of a coupled active multiplier antenna array on its matching method for the second-harmonic output power is developed. By using the harmonic-balance method and weakly coupled oscillator dynamic theory, one can well predict its second-harmonic output power, matching condition and phase distribution between array elements. Impedance matching using the large-signal and small-signal analysis concept can increase the output power about 3dB. By further considering the clipping effect of the bias condition, the output power can be increased by about 6 dB to be 9.5 dBm. The measurement results are shown to be in good agreement with simulation results.
