Patent attributes
A wireless transmission circuit includes a first induction circuit, a second induction circuit, a detection circuit, a first signal adjustment circuit, and a third induction circuit. The first induction circuit is configured to receive a first signal outputted from a power amplifier. The second induction circuit is configured to output the received first signal as a second signal. The detection circuit is configured to detect a common mode signal associated with the first signal. The first signal adjustment circuit is configured to adjust a phase or an amplitude of the common mode signal to generate a third signal. The third induction circuit is configured to receive the third signal and be coupled to the second induction circuit to reduce a second harmonic in the second signal.
