RF Ku, /,,. RF 10 W, GaN.,, 6 SAW. AWR. Abstract In this paper, we designed a RF transceiver operating up to 200 km operating range and 45 Mbps data rate. The RF transceiver operates in Ku band and composed of up/down converter, high power amplifier, front-end elements. To satisfy the operating range of RF transceiver, 10W power amplifier was required and realized by using GaN power amplifier. Moreover, to mitigate mutual interference for different bandwidth signals due to the adaptive transmission speed control function, SAW filter bank structure was used. To verify system requirement satisfaction AWR simulation tool was used. Key words: Ku-Band, Transceiver, Fractional-N, Spectrum Mask, SAW Fiter. 서론 (Common Data Link: CDL) / Signal Intelligence 1991.,,, 10, 200 kbps (return link) 25, 10.71 Mbps 45 Mbps (forward link).
