"A design of a duplexer using non-uniform shunt stubs as resonators is presented in this report. The design procedure uses lumped element, low-pass prototype filters realized in TEM transmission line medium. The resulting duplexer is very compact, having relatively non critical manufacturing tolerances and a high stop-band attenuation which is necessary to isolate transmit and receive frequency bands. The duplexer has been developed without inclusion of any tuning screws. The theoretical performance of the duplexer and the measured results show good agreement"--Abstract.
