Improvement of analytical method of harmonic frequency effects of IMPATT diode
Abstract
The harmonic frequency effects of IMPATT diodes with large signal amplitudes are analyzed by Taylorexpanding the nonlinear terms of the diode differential equation into a Fourier series. The ionization coefficient of the nonlinear diode element is approximated linearly by the first and second order harmonic terms of the Taylor series. While this method requires up to ten times longer computation times than for the first order approximation, the second order approximation is applicable for computation of large signal amplitudes with very small error for the breakdown electric field up to 0.25. In addition, the second order approximation shows improvement in the approximation of nonlinear terms.
