  • Circuit for correcting group delay at microwave frequencies
    Patent number: 4988962
    Abstract: A microwave frequency group delay corrector operates by reflecting the microwave on a correcting complex impedance (jx). It makes use of a power divider (13), of the Wilkinson type. The complex impedance (20) is connected to the port (14) which is normally the inlet port to the power divider (13). The microwave (E) is applied to one of the other two ports (15), and the remaining other port (16) is used as the port from which the phase corrected outlet microwave (S) is taken.
