Patent ID: 7157993

Claim:
A 1:N micro-electromechanical (MEM) switch module, comprising: a substrate, a signal input line on said substrate for receiving a signal to be switched, and N MEM switches on said substrate, each of said switches having an input contact and an output contact on said substrate which are separated by a gap, and a movable contact which provides an electrically continuous signal path between said input and output contacts when said switch is actuated, each of said input contacts connected to said signal input line via respective switch input lines and each of said output contacts connected to respective signal output lines, wherein each of said switch input lines has an associated effective capacitance, said switch input lines designed such that the inductance of each switch input line is matched to its effective capacitance at a given design frequency such that the impedance of each of said input lines is largely resistive at said design frequency.
