摘要：A multi-level quadrature (I/Q) mixer for use in a communication system such as apaging device, where the mixer includes first and second I/Q downconversions followedby demodulation. The first I/Q downconversion converts an I/Q signal pair to a first IF,and the second I/Q downconversion converts an I/Q signal pair to a second IF. The first IFmay or may not be the center frequency depending on the number of subchannels in thesingle channel being downconverted.
