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

摘要

PURPOSE: A matching segment circuit for a radio frequency and a radio frequency integrated device using the same are provided to improve the performance of a duplexer by using a duplexer including a matching segment circuit for an RF.;CONSTITUTION: A matching segment circuit for an RF(Radio Frequency) comprises an input terminal(110), a parallel segment(120), and a serial segment(130), and an output terminal(140). The input terminal is composed of a single input port. The input terminal is connected to an external first RF device. The parallel segment is composed of a parallel structure of a first inductor(123) and a first capacitor(121). The serial segment is serially connected to the parallel segment. The serial segment is composed of a second inductor(131) and a second capacitor(133). The output terminal is composed of a single output port.;COPYRIGHT KIPO 2012
