15. A transceiver comprising:
a digital transmit circuit configured to generate at least one baseband transmit signal;
at least one mixer configured to generate a radio frequency transmit signal based on providing frequency upconversion to the at least one baseband transmit signal; and
a local oscillator configured to pre-distort the radio frequency transmit signal by providing one or more shaped clock signals to the at least one mixer.
