A satellite is configured for use in space so as to receive RF signals, convert them to a different frequency range, and retransmit the converted RF signals. The satellite comprises a payload area supporting a motherboard structure with a plurality of frequency converters supported on it. The frequency converters are each connected with an antenna system of the satellite so that each of them receives a respective RF input signal. A local oscillator source supported on said motherboard structure generates a local oscillator signal, and a motherboard in the motherboard structure receives the local oscillator signal and transmits it through the motherboard to each of the frequency converters. The frequency converters each convert the respective RF input signal to a respective RF output signal using the local oscillator signal and transmit the RF output signal to the antenna system so as to be transmitted wirelessly.
