Summary:
In this paper, a wideband RF transceiver system with adjustable bandwidths and center frequencies is presented. Because the proposed wideband RF carrier can control an RF spectral shape without changing the modulation scheme, the transmitting channel power can be adjusted by changing the channel bandwidth. From the experimental results, the proposed system has been evaluated from PER (Packet Error Rate) tests to measure a sensitivity level for each flexible channel spectrum. In addition, the OOK-modulated signals with 64 kbps data rate and 50 % duty-cycle have been successfully transmitted by flexible channel frequency and bandwidth. The proposed system has established the controllability of the emitting power by adjusting bandwidth instead of peak power on conventional systems.
