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.
