Abstract
A multi radio access technology (RAT) radio circuit is provided. The multi RAT radio circuit can support concurrent transmission of radio frequency (RF) transmit signals modulated based on a first RAT and a second RAT and concurrent reception of RF receive signals modulated based on the first RAT and the second RAT. The multi RAT radio circuit splits each RF transmit signal into an in-phase transmit signal and a quadrature transmit signal. The determined phase offset is so configured such that the multi RAT radio circuit can effectively suppress an IMD(s) located above and below a transmit band(s) of the RF transmit signals. By suppressing the IMD(s), it is possible to improve RF performance of the multi RAT radio circuit regardless of whether the RF transmit signals and the RF receive signals are communicated in a contiguous or non-contiguous RF spectrum.
