The disclosed polar modulation transmitter circuit is configured to generate an output signal having a transmission frequency that minimizes crosstalk effects between different transmission bands (e.g., Bluetooth, GSM, UMTS, etc.). In particular, a polar modulation transceiver circuit, having an amplitude modulated (AM) signal and a phase modulated (PM) signal, comprises a digitally controlled oscillator (DCO) configured to generate a DCO signal having a DCO frequency. The DCO signal is provided to one or more frequency dividers that are configured to selectively divide the DCO signal to generate various lower frequency signals, used to select a sampling rate for a DAC operating on the AM signal and an RF carrier signal frequency, which result in an output signal having a frequency that does not interfere with other RF systems on the same IC (e.g., that falls outside of the downlink frequency of other RF systems). Other systems and methods are also disclosed.
