Abstract
A coupling network for coupling a signal at a frequency from a voltage source to a load. The voltage source has a source resistance. The load has a load resistance and a load reactance. The ratio of the load reactance to the load resistance greater than 100. The coupling network includes a reactive element and a delay circuit. The reactive element is arranged in series with the load to resonate with the load reactance at the frequency. The delay circuit is between the reactive element and the source, has a delay equivalent to a quarter wave length transmission line at the frequency and has a characteristic impedance equal to the square root of the product of the values of the load resistance and the source required resistance.
