The Rat Race circuit operates as a hybrid circuit at the center frequency, but as the frequency of operation becomes discrepant from the center frequency,its input immittance is no longer real,but contains an imaginary part which leads to poor matching and to poor isolation. Such defects can be avoided by means of susceptance compensation or reactance compensation. A practical method of susceptance compensation can be realized in the form of shunt inductive susceptance,connected to each port of less self admittance. Another method will be by reactance compensation with series capacitance. There are other methods of broadbanding, e・g. by making the image immittance diagonany and by selecting the terminating immittance in accordance with the image immittance. These methods of broadbanding may be combined, leading to composite compensation techniques.
