REPEATER APPLIED ELEMENTS FOR MOBILE STATION

摘要

A repeater to which elements for a mobile communication terminal is provided to implement filters, LNAs and mixers by using elements of the mobile communication terminal, which has lower power consumption property, better power property, and small signal loss property. A repeater to which elements for a mobile communication terminal are applied comprises LNAs(Low Noise Amplifier, 203,207,233,237), mixers(205,209,213,221,235,239,243,251), SAW(Surface Acoustic Wave) filters and PAMs(Power Amplifier Module, 223,253). The LNAs(203,207,233,237) amplify low noises of inputted signals. The mixers(205,209,213,221,235,239,243,251) convert the inputted signals into specific frequency band signals. The SAW filters enhance isolation property of a guide band by adding an LC matching circuit and controlling a position of passed band. The PAMs(223,253) add the first matching circuit and the second matching circuit to an RF inputting end and an RF outputting end, respectively for making individual tuning possible.
