Self-Cascadable Phase Shifter

摘要

A self-cascadable phase shifter having a two corresponding pairs of input and output pins. Each pair of input and output pins are interconnected by phase delay circuitry that is isolated from phase delay circuitry interconnecting the other pair of input and output pins so that each pair of input and output pins produces, for example, a 90 degree phase shift. The resulting phase shifter can be used to produce a 90 degree by using one pair of input and output pins or cascading both pairs of input and output pins to provide a 180 degree delay.

主权项

1. A phase shifter comprising:
a body supporting a pair of opposing ground pads, a first input, a first output, a second input and a second output; first phase delay circuitry positioned in the body and electrically interconnecting the first input with the first output to produce a first predetermined phase delay in a signal provided to the first input; and second phase delay circuitry positioned in the body and electrically interconnecting the second input with the second output to produce a second predetermined phase delay in a signal provided to the second input; wherein an electrical connection between the first output and the second input will produce a third predetermined phase delay in a signal that is the sum of the first predetermined phase delay and the second predetermined phase delay.
