Frequency planning for digital power amplifier

Systems and techniques relating to wireless communication devices and digital power amplifiers include, according to an aspect, a device including: modulation circuitry of a radio frequency transmitter having a local oscillator frequency; a digital power amplifier coupled with the modulation circuitry; and a clock input coupled with the digital power amplifier; wherein the clock input provides a clock signal to the digital amplifier at a sampling clock frequency; and wherein the local oscillator frequency is an integer multiple of the sampling clock frequency.
