| Abstract | This paper addresses the fundamentals of RF switches, providing a comparison between semiconductor and RF microelectromechanical systems (MEMS) switches. The basis of comparison is introduced by defining a figure of merit that is a function of the off-state capacitance and the on-state resistance. A simple transmission-line model is presented to illustrate the impact of the switch off-state capacitance on the switch isolation and frequency range of operation. The figure-of-merit analysis given in this paper demonstrates that RF MEMS switches have superior insertion loss and isolation performance compared to MESFET and p-i-n diode switches. The paper also addresses several other design considerations besides insertion loss and isolation for selecting the right RF switch. A discussion is included on the potential use of RF MEMS switches in satellite and wireless applications. |
