Abstract

PURPOSE:To attain economization by connecting power amplifiers to plural transmitters in a way that amplifiers amplify every other transmission wave in the sequence of the frequency in common to decrease the number of the power amplifiers and to reduce the power consumption of the amplifiers. CONSTITUTION:Transmitters 11-14 have different transmission frequencies f1-f4 respectively through the frequency setting and each transmitter modulates an input signal fed to an input terminal (IN1-IN4) individually respectively and changes the frequency. The power amplifiers 15, 16 are provided to the transmitters 11-14, the two each transmitters are connected to each power amplifier and it is configurated that each power amplifier amplifies two transmission waves respectively. Thus, an inexpensive power amplifier with less linearity performance is employed, and the number of the amplifiers is halved or below in comparison with the number of the transmitters, thereby economizing the circuitry.
