PROBLEM TO BE SOLVED: To provide a novel configuration capable of successive synchronous switching in a redundant baseband provided with plural A/D converting circuits and a plurality of baseband signal processing circuits to be used for wireless communication equipment for processing signals from a wireless part. SOLUTION: In the redundant baseband, with which the current system of one set and the current system of the other set in the baseband signal processing circuit mutually output input signals as auxiliary input of opposite circuits and the standby system of one set and the standby system of the other set in the baseband signal processing circuit mutually output input signals as auxiliary input of opposite circuits, a data selecting part is provided in each of baseband signal processing circuits, a received data entry (RX-A/D), an A/D state notice signal and a received data entry (RX-BB) from the other baseband signal processing part are individually inputted and further, a forced switching instruction signal instructing forced system switching and a synchronous switching instruction signal instructing system switching synchronized with a processing signal are connected.
