  1. TE01 disk-loaded guide (coaxial) load • No electric field terminating on a conductor. • No axial currents. • No currents at wave-guide disk interface • Attenuator and filter. • Broadband matching to disk loaded guide.

  2. match =Z

  3. Obtain disk radius ra and mechanical period pz of the matching cells. • With a given ra vary pz to obtain a 90 degree phase advance at 11424 MHz. Note Z. • Obtain functions ra(Z) and pz(Z).( Polynomial ) • Insert the values of Z that are required to yield a Butterworth function for Gin and obtain ra and pz for the matching cells. • Cascade the cells.
