发明名称 RF device and method with improved active load modulation capability
摘要 There is described an RF bidirectional communication device utilizing active load modulation, the device comprising (a) a resonance circuit including an antenna (326), and (b) a control unit (322) for controlling communication of the device, including switching between a transmission mode and a receiving mode, wherein the control unit is adapted to (c) modify a configuration of the resonance circuit such that the resonance circuit has a first resonance frequency (f 0 ) when the device is in the transmission mode and a second resonance frequency (f 0 +”f) when the device is in the receiving mode, and (d) modify the configuration of the resonance circuit such that a Q-factor of the resonance circuit is periodically decreased while the device is in the transmission mode. There is also described a corresponding method and a system comprising a RF device and a reader/writer device. Furthermore, there is described a computer program and a computer program product.
