TRANSMITTER FOR SUPPORTING MULTI-MODE AND MULTI-BAND USING MULTIPLE RADIO FREQUENCY DIGITAL-ANALOGUE CONVERTERS(RF DACS) AND CONTROL METHOD OF THE TRANSMITTER

摘要

Multinomial wireless frequency: digital number-analogue converter provides mode and much inverse machines of delivering letters supported in more. According to day embodiment, machine deliver letters with the first wireless frequency digital number digital number number-analogue converter (RF DAC) of the mind number transmission of first frequency regicide first, the second radio frequency digital-to-analog parallel operation of second signal is shown in the distinguishing second frequency regicide of the 1st frequency regicide. The scaling program of the wireless frequency digital-to-analog converter for wireless frequency digital number-simulation accommodation device frequency example patterns (impdaningmatching mode) movement that data transfer mode (data transmison mode) operates in first wireless frequency numeric digit-analogue converter and the second wireless frequency digital number-analogue converter may include Impedance control portion
