<p>PROBLEM TO BE SOLVED: To eliminate non-linear distortion of a transmission line by providing a receiving line with a switching circuit as a circuit configuration in plural branches diversity system and performing radio communication through a radio base station or inter-radio terminal station direct radio communication without providing the transmission line with a switching circuit. SOLUTION: This digital radio equipment having a sending part in a 1st frequency band and a receiving part in 1st and 2nd frequency bands is provided with a branch which connects a 1st receiver in the 2nd frequency band to a 1st antenna 101 to which the sending part is connected, a branch which connects a 2nd receiver that receives a signal in the 1st frequency band a signal in the 2nd frequency band with the switching of switching circuits 122 and 126 to a 2nd antenna 121 and a controlling part 157 which switches the switching circuits. It has at least a receiving part as a receiving diversity configuration of the two branches, controls the switching circuits of the 2nd receiver and switches a diversity receiving function that receives a signal in the 2nd frequency band and a non-diversity receiving function that receives a signal in the 1st frequency band.</p> |
