Abstract

This work presents an experimental investigation of phase noise in a custom-designed distributed transmitter array at 28 GHz implemented using 0.13μm SiGe BiCMOS technology. Frequency alignment among radio front-ends is realized via a charge pump phase-locked loop (CP-PLL), while phase coherence and wireless transmission are achieved using a high-resolution continuous phase shifter and integrated power amplifier (PA). The proposed system exploits coherent transmission of distributed signals synchronized to a common reference to suppress uncorrelated phase noise components at the receiver location, achieving phase noise improvement theoretically bounded by 10·log(N).
