Problems solved by technology

[0026] However, the above-mentioned UMTS method is a new-generation mobile communication method of the 3GPP method, and uses multimedia (MULTIMEDIA) for communication, so it is received through the above-mentioned converter (40) and antenna duplexer (30) in a state of a lot of power consumption. The corresponding high-frequency signal is transmitted, so there is a problem that the path loss (LOSS) of the high-frequency signal increases, and at the same time, in order to obtain the same output, it consumes a lot of power

Abstract

This invention relates to a device and method for reducing UMTS high frequency path loss in a double mode mobile phone compatible with GSM and UMTS. The structure of the device characterizes that a control part monitors and controls each function part of a mobile phone, and outputs the path set controls signals, the path part separates UMTS high frequency signals of DCS and GSM high frequency signals into their own paths for input / output based on the monitor and control of the control part, the duplexer and / receives UMTS signals, DCS emits / receives DCS signals, GSM emits / receives GSM signals.

Description

technical field [0001] The invention relates to a high-frequency converter of a mobile phone, in particular to a mobile phone high-frequency path setting device and method for reducing path loss in a dual-mode (DUAL MODE) mobile phone compatible with GSM and UMTS used in Europe. Background technique [0002] The mobile communication system used in Europe (EUROPE) adopts the GSM (GSM: Global System for Mobile Communications, GLOBAL SYSTEM FOR MOBILE COMMUNICATION) method, which is a time division multiple access (TDMA) method, and some use the 900MHz wireless frequency band, and some use the 1.8GHz For the wireless frequency band, the above-mentioned 1.8GHz frequency band is used to expand wireless frequency resources, also known as GSM1800 or DCS (Digital Cordless System, DIGITAL CORDLESS SYSTEM), which integrates the above-mentioned GSM and DCS, and PCS (Personal Communication System, PERSONAL COMMUNICATION SYSTEM) ) concept operation. [0003] In Europe, the third-generat...
