Abstract

Techniques are disclosed for producing RF signals from baseband signals. For instance, an apparatus may include an intermediate frequency (IF) signal generation module, and an upconversion module. The IF signal generation module produces an analog IF signal from a digital baseband signal. In turn, the upconversion module generates a radio frequency (RF) output signal from the analog IF signal. The upconversion module may include a translational phase locked loop (PLL) to receive the analog IF signal and to produce the RF output signal. The RF output signal may be for transmission in a wireless communications network, such as a cellular network.
