Abstract
This paper proposes the integration of digital modulator and power amplifier using switching power converter. The proposed concept can be referred as Digital Power Modulator. The aim is to improve the energy efficiency in modern digital communication systems. The converter has specification of 48 V input voltage, 50 ohm output load, 30 W output power, 500MHz switching frequency. The voltage stresses in semiconductor devices and capacitors will be analyzed in this paper. In addition, the behavior of current and voltage waveforms will be simulated and analyzed with PSPICE software. The combination analysis of the converter in DCM (Discontinuous Conduction Mode) operation to modulate current and voltage at 50 ohm load in a resonant mode based on one cycle amplitude shift keying digital modulation technique is also provided. Simulation results confirm that one cycle amplitude shift keying and phase shift keying modulation techniques with data rate of 500 Mbps can be shaped using the proposed switching power converter.
