Abstract
In an embodiment, a communications system includes a transmitter including a digital beamforming baseband section including a digital mixer, the digital beamforming section configured to receive an input signal to be transmitted, the input signal at a baseband frequency; and a modulation section electrically coupled to the digital beamforming baseband section, the modulation section including an up converter configured to receive a local oscillator signal at a local oscillator frequency. The digital mixer is configured to apply a baseband frequency shift to the input signal to generate a baseband frequency shifted input signal at a different frequency from the baseband frequency. The up converter is configured to up convert the baseband frequency shifted input signal based on the local oscillator signal to generate a modulated signal at a carrier frequency, wherein the local oscillator frequency is different from the carrier frequency.
