IPC: H03F3/60
Filed: 2013-04-26
Abstract: The present invention relates to an intermodulation cancellation apparatus for a passive component, comprising a power coupler, an adjusting module, and a nonlinear component. The intermodulation cancellation apparatus uses one port for input and output. The power coupler couples a transmitted signal from the passive component by using the input and output port. The adjusting module and the nonlinear component separately perform first-time processing for the coupled transmitted signal. After the signal undergone with the first-time processing is reflected at an end of the intermodulation cancellation apparatus, second-time processing is performed for the signal, to generate a power signal containing a second intermodulation cancellation signal. The second intermodulation cancellation signal in the power signal has the same frequency and level as and a different phase from an intermodulation signal of a transmitted signal in the passive component. The power signal and the transmitted signal in the passive component overlap and are output to the passive component from the input and output port. The present invention can cancel the intermodulation signal of the passive component in the whole working band.
