Abstract
A signal processing apparatus and related transceiver circuit are disclosed. The signal processing apparatus includes a power amplifier circuit and a transceiver circuit. The transceiver circuit is configured to generate multiple composite signals each having a respective one of multiple inverted intermodulation product terms. The power amplifier circuit includes multiple power amplifiers each configured to amplify a respective one of the composite signals. By including the inverted intermodulation product terms in the composite signals prior to amplifying the composite signals, it is possible to offset intermodulation product terms inherently caused by nonlinear responses of the power amplifiers, thus helping to reduce spectrum degradation in the signal processing apparatus.
