ABSTRACT:
Radio section103multiplies 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 switch104. Switch104switches between frequency conversion sections fA to fD and between antennas A to D to connect, and timing control section105outputs a timing control signal to switching control section107at time intervals for which timer106is preset. Switching control section107controls the switching of switch104according to switching patterns which are preset in switching pattern storage section108and which are each indicative of a connection relationship between antennas A to D and frequency conversion sections fA to fD.
