Abstract
An orthogonal signal generator includes a first stage phase shifting circuit and a second stage phase shifting circuit. The output end of the first stage phase shifting circuit is connected with the input end of the second stage phase shifting circuit, an impedance of the first stage phase shifting circuit is adjustable based on the frequency of a first input signal. The first stage phase shifting circuit is configured to phase-shift the first input signal by a first phase shifting angle to generate a first phase shifting angle signal. An impedance of the second stage phase shifting circuit is adjustable based on a frequency of a second input signal. The second stage phase shifting circuit is configured to phase-shift the phase-shifted second input signal by a second phase shifting angle to output an orthogonal signal with the corresponding frequency.
