Abstract
Radio sectionmultiplies modulated transmission signals A to D respectively by a carrier with a frequency of fA, fB, fC or fD, thereby performs the frequency conversion, and outputs the resultant signals to switch. Switchswitches between frequency conversion sections fA to fD and between antennas A to D to connect, and timing control sectionoutputs a timing control signal to switching control sectionat time intervals for which timeris preset. Switching control sectioncontrols the switching of switchaccording to switching patterns which are preset in switching pattern storage sectionand which are each indicative of a connection relationship between antennas A to D and frequency conversion sections fA to fD.
