Patent ID: 7298233

Claim:
A variable phase shifter module, comprising: a first main PCB having an input trace coupled to a first wiper junction; a first arcuate trace extending between a first output trace and a second output trace on the first main PCB, the first arcuate trace having an arc center proximate the first wiper junction; a first wiper PCB having a linking trace thereon; the first wiper PCB rotatably coupled to the first main PCB proximate the first wiper junction with the linking trace facing the first main PCB; the linking trace coupling the first wiper junction with the first arcuate trace; and an arcuate edge guide surface formed in the first main PCB having an arc center proximate the first wiper junction; and a clip coupled to the first wiper PCB to bias the first wiper PCB against the first main PCB about the arcuate edge guide surface.
