A Study of RF Absorber for Anechoic Chambers Used in the Frequency Range for Power Line Communication System
نویسنده
چکیده
Power line communication (PLC) system is spreading as a new communication system without providing new infrastructure for network communication. However, It is needed to investigate the EMI problem caused by PLC, and it is often tested in an anechoic chamber and an open area test site (OATS). The semi anechoic chamber lined ferrite tiles used for EMC testing is not generally designed in the frequency range from 2MHz to 30MHz used for PLC system. This paper presents characteristics of conventional ferrite absorber which are used for a semi anechoic chamber (SAC) and site attenuation of the semi anechoic chamber in the frequency range used for PLC system.

متن کاملA Hysteretic Two-phase Supply Modulator for Envelope Tracking RF Power Amplifiers
In this paper a two-phase supply modulator suitable for envelope tracking power amplifier is presented. The designed supply modulator has the linear assisted switching architecture. Two-phase architecture is used in order to reduce the output switching ripples. The proposed architecture uses hysteretic control instead of pulse width modulation (PWM) which significantly reduces the circuit compl...
