500 Mbps One Cycle On-Off Keying Modulator Using Resonant Power Converter

This paper presents the integration of digital modulator and power amplifier using resonant 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 of 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 On-Off Keying digital modulation technique is also provided. Simulation results show that the On-Off Keying modulation with data rate of 500 Mbps can be produced using the proposed resonant power converter.
