Abstract:
A radio unit for unsynchronized Time Division Duplex (TDD) multi-band operation in a wireless communication system. The radio unit comprises a first resonator arrangement comprising one or more resonators tuned for operating at a first frequency band. A first terminal of the first resonator arrangement is coupled to an antenna element. The radio unit further comprises a second resonator arrangement comprising one or more resonators tuned for operating at a second frequency band. A first terminal of the second resonator arrangement is coupled to the antenna element. The radio unit further comprises a tunable resonator arrangement comprising at least four tunable resonators. The at least four tunable resonators in the tunable resonator arrangement are tuned according to different operating modes.
