The C-BUC is a high performance, cost-effective RF transmitter designed for satellite communication with high speed transmission capability suitable for both television and high speed data communication. Base-band signals are modulated onto L-band frequency and multiplexed with 10 MHz reference and DC supply on the center conductor of the IF cable. It is then up converted and amplified in the C-BUC for transmission to the satellite via an antenna dish.
The C-BUC serves to up convert the L-band transmit signal to the C-band transmit frequency range and to to amplify it by an integrated SSPA. Power levels range from 1 mW to 500 W output. It is designed with low power consumption,
well suited for systems and applications where power is of prime concern. With low pulse
mode phase perturbation, it is extremely useful for systems that require burst mode
The transmit output waveguide is WR137 with groove and O-ring is provided. A yellow
transparent tape is laminated onto the wave guide; together with the O-ring and proper
installation, this prevents water ingress through the wave guide.
