PURPOSE: A duplicating device of a high power amplifier(HPA) in a WLL(Wireless Local Loop) system is provided to continuously operate the system, by duplicating a redundancy HPA operated independently in each channel, so that channels can share the HPA in a base station of the WLL system standardizing 2FA(Frequency Assignment). CONSTITUTION: A duplicating device of a high power amplifier(HPA) in a WLL(WirelessLocal Loop) system implements a duplicating device, so that channels can share a redundancy HPA for being independently composed in each channel. The duplicating device performs duplicating operation through the redundancy HPA, corresponding to a self channel about one HPA channel when malfunction of 2 HPAs is generated. The duplicating device performs duplicating operation through the redundancy HPA, corresponding to other's channel about the rest one channel.
