Abstract
A differential time delay shifter may comprise a 1-to-N switch, where N is an integer greater than 1. The switch may have a pole contact, N throw contacts, and a pole arm to selectively couple the pole contact to one of the throw contacts. One throw contacts may be a first throw contact at a first switch position, and one throw contacts may be a last throw contact at a last switch position. The shifter may further comprise one or more transmission lines, each of which is electrically connected between two of the N throw contacts. The shifter may further comprise a source configured to generate an electromagnetic signal. The source may be electrically coupled to the pole contact, to convey the signal to the pole contact. The shifter may further comprise one or more loads, a first of which is electrically coupled to the first throw contact.
