摘要： A monoblock dielectric duplexer comprises resonant holes. Conductive electrodes and couplers are formed on one side of the dielectric block, whose other sides are covered with a conductive material. The conductive electrodes in a transmit-filtering portion are formed in an inter-digitating manner while the conductive electrodes in receive-filtering portion are formed to be of pad-shape. In the duplexer, capacitances of capacitors comprised of the conductive electrodes are easily and accurately set to desired values by determining the number and/or the lengths of fingers that the inter-digitating electrodes have.
