Abstract
A delay line for microwaves, whose transfer function is subject to phase variations with changes in ambient temperature, is connected in cascade with a transmission line whose phase varies in the opposite sense. The transmission line, which may be integrated with the associated delay line in a common microstrip structure, is of such length as to maintain the overall phase shift substantially constant within a certain temperature range.
