Abstract:
The digital transmitter (DTX) offers both high power efficiency and frequency flexibility by merging signal amplification and modulation in the switching power amplifier. Yet, the back-end high-speed digital baseband interface is challenging and bulky for obtaining low out-of-band noise. This brief provides an analytical study of the DTX linear interpolation technique, which can be easily utilized for optimizing the replica rejection and noise-filtering capabilities of the DTX.
