Abstract
A radio frequency switch disposed over a substrate having ground plane conductors disposed over an opposite surface thereof is described. The switch has at least two terminals, and includes a plurality of pairs of transistors, each one of said transistors coupled between a reference potential and a common transmission line which is coupled to one of the pair of terminals. A pair of topside conductors are disposed over the substrate to couple the transistors through plated vias to a bottom ground plane conductor. The switch further includes a series connected transistor disposed between the r.f. line and a second one of the terminals of the circuit.
