Charge Effects and Transient Simulation of p-HEMT Meander Gate Switches

This paper presents a simulation of the transient behavior of a filtronic SP6T switch. By employing a non-linear switch model a representation of the switching dynamics is presented. The simulations predict that the changing control voltages has quickly attenuate the fundamental power, however harmonic performance is dependant on the total bias applied to the switch and hence relaxes to its steady state condition 0.15mus after the control voltages have settled. Within this paper we demonstrate the importance of understanding the behavior of the switch during transitions between equilibrium conditions with respect to the radiated spectral content
