PURPOSE: A device for sharing duplexing HPA(high power amplifier) of multi-channel radio port is provided to divide and combine the outputs of extra HPA using a combiner, thereby compensating signal loss between normal transfer paths and duplexing transfer paths. CONSTITUTION: A device for sharing duplexing high power amplifier of multi-channel radio port comprises a path controller(170,270), a front 3:5 switch unit(100), a rear 1:2 switch unit(140), a front combiner(130) and a rear 3:4 switch(160). The path controller(170,270) monitors the state of the HPA of one channel and transceives state information with the path controllers of another channels. The front 3:5 switch unit(100) consists a 3:4 switch(110) and a 1:2 switch(120). The rear 1:2 switch unit(140) switches the filters of respective HPAs in accordance with the control of the path controller. The front combiner(130) combines one of outputs of the rear 1:2 switch and one of outputs of a rear 1:2 switch of the HPA. The rear 3:4 switch(160) switches the outputs of the HPA and the rear combiner and the filters.
