摘要: A passive microwave component with constant impedance and electrically adjustable phase length utilizes a microstrip or stripline transmission line geometry incorporating composite dielectric having both ferroelectric (FE) ferromagnetic (FM) properties. These properties can be varied externally applied electric magnetic fields such that the (or electrical length) of without varying characteristic line. Thus, tuned adversely affecting match. The used in devices as shifters, frequency filters, directional couplers, power dividers combiners, impedance-matching networks.
