摘要：
The theory of a class of rational Chebychev functions is presented, forming the basis of optimum approximation functions that determine the response of lumped element quadrature hybrids of suitable design. Analytical solutions are presented, allowing the designer to determine the order of function required to meet a given divider specification and to predict the performance: over frequency.
