Abstract

For pt. 1 see ibid., p. 70-73 (2002). An analysis is introduced for the third-order-intermodulation (IM3) cancellation induced by the emitter-terminations, which has been observed in part I of this paper. The analysis shows that the IM3 can be perfectly cancelled if the emitter impedance at the second harmonic and the sub-harmonic frequencies are terminated properly and if the effect from qbc is negligible. When the effect of qbc cannot be neglected, optimized source and load harmonic terminations are proposed to minimize the qbc effects. Increasing the source impedance at the fundamental frequency is found effective in minimizing the residual IM3 that is not cancelled from the proposed terminations.
