Abstract
A remote ground terminal for transmitting a modulated data signal to a satellite. The remote ground terminal includes an outdoor unit comprising an input port for receiving a modulated data signal, a housing having an upper portion and a lower portion which comprises a waveguide. The outdoor unit further comprises a transmitter module for amplifying and multiplying the modulated data signal so as to produce the modulated carrier signal. The transmitter is mounted in the lower portion of the housing so as to be positioned above at least a portion of the waveguide. The outdoor unit also comprises a probe having a first and second end, with the first end being disposed in the transmitter module. The probe receives the modulated carrier signal generated by the transmitter module. The second end of the probe extends from a lower surface of the transmitter module into the waveguide. The probe is operative to couple the modulated carrier signal directly into the waveguide disposed in the lower portion of the housing. The modulated data signal is then coupled to an antenna coupled to the output of the waveguide via a feedhorn, and transmitted to the satellite.
