Chebyshev Synthesis
Chebyshev function is widely used in microwave field,
but I can only use the reulted tables and have no ability
to synthesize by myself.For example,give you an S21
function which contains chebyshev function,how to synthesis
the related RF circuit?
thanks.

This function is described in detail in many filter synthesis books. One that is easy to understand is Introuction to Filter Theory by David E. Johnson.
Chebychev was a steam railroad engine design engineer in Russia. These equations started out for designing the steam valve that shunted the steam to alternating sides of the pistons driving the wheels of the railroad engine.
Maybe you should make reference to many books,like upstairs,you can get the basic concepts for sythesis Chebyshev or Eilliptic function filter,but in application,you should also know how to achieve the coupling cofficient using iries of aperture,you may get help to this book:
