MATCHING SEGMENT CIRCUIT APPLIED TO RADIO FREQUENCY AND RADIO FREQUENCY INTEGRATED DEVICES USING THE MATCHING SEGMENT CIRCUIT

摘要

PURPOSE: matching segment circuit includes the RF circuits for matching segment by using duplexer using the identical performance for improving duplexer with radio frequency integrated device for radio frequency. ;CONSTITUTION: the RF (radio frequency) of compatible portion circuit includes input terminal (110), parallel segment (120), serial section (130) and output terminal (140). Input terminal is carried the input terminal and is connected to external first RF devices by individually inputting. Parallel segment by parallel organization the first inductor (123) and first capacitor device (121). Series block concatenation has gone up parallel segment. The series block is by the second inductor (131) and first capacitor device (133). Output end is by individually exporting carrying;The 2012 of copyright KIPO submissions
