Abstract: An apparatus and method for mitigating polarization mismatch in reflector antenna systems. A feed unit is configured to determine a polarization mismatch between a first polarization associated with a first wave and a second polarization associated with a reflector unit. The feed unit pre-distorts the first wave to achieve a compensated polarization for reducing and/or eliminating a polarization mismatch. The pre-distorted first wave having the compensated polarization is used to illuminate the reflector unit. A re-radiated wave is reflected by the reflector unit. Furthermore, the level of the re-radiated wave is increased as a result of the pre-distortion.

Abstract: A VSAT system modem has three chips and a block. A first chip generates a modulated carrier signal and a local oscillator signal having a same frequency. A second chip receives the local oscillator signal from the first chip and produces a reference signal. The reference signal and the modulated carrier signal are received by the block, which multiplexes the reference signal and the modulated carrier signal onto a single inter-facility link. The single inter-facility link transmits the modulated carrier signal and the reference signal and provides a received modulated carrier signal to a third chip. The first chip may be a synthesizer/modulator chip, the second chip may be a prescaler chip, the third chip may be a DVB-S2 tuner chip and the block may be a multiplexer. The chips may be standard semiconductor chips. Alternatively, a digital-to-analog converter chip may produce the reference signal.

Abstract: A digital phase shifter is described where each bit of the phase shifter has a circuit block including one PIN diode in parallel with one transmission line. The phase shifter requires only one PIN diode and one transmission line per bit circuit block. Each PIN diode behaves like a simple switch for phase shifting. When the PIN diode is forward biased ("on" state), current flows through the PIN diode and the RF signal is not phase shifted. When the pin diode is not forward biased ("off" state), current flows through the transmission line parallel to the PIN diode and the RF signal is phase shifted by the transmission line. The digital phase shifter may have n circuit blocks in series, and adjacent PIN diodes may share a current when both are on. The phase shifter may be implemented in a phased array or reflect array antenna including multiple phase shifters.

Abstract: A device and method are described for duplex satellite communication over a single satellite antenna. A satellite ground terminal may utilize a frequency-selective surface module including a frequency-selective surface as a subreflector acting as a frequency diplexer to separate signals received and/or transmitted by a first feed and a second feed of a satellite ground terminal, where each feed has a separate antenna horn. The frequency-selective surface module may be used in combination with a second subreflector such that a first feed and a second feed of the satellite ground terminal are implemented on the same side of the frequency-selective surface module.

Abstract: Systems and methods disclosed herein provide techniques for reducing quantization errors and side lobe levels in phased array antennas. The states of a quantized phase shifter of a phased array antenna may be dithered to achieve a time-averaged value that reduces quantization errors. By rapidly switching between the different states of the quantized phase shifter, a time-average value close to a desired phase state may be achieved with a low resolution phase shifter.

Abstract: A linear radio and a method for performing automatic level control are provided. A demultiplexer, within the linear radio, receives multiplexed signals from an indoor unit via a cable connecting the indoor unit with the linear radio. The demultiplexer demultiplexes the multiplexed signals to produce a transmit signal of an intermediate frequency. A variable gain amplifier within the linear radio, receives the transmit signal and a signal from an operational amplifier and produces the transmit signal with a changed gain, which is provided to a coupler. The coupler provides the transmit signal with the changed gain to a mixer and a power detector simultaneously. The power detector produces a second signal, which is provided to the operational amplifier, thereby forming a closed automatic level control loop. In some embodiments, the demultiplexer produces a power control signal, which is provided to the operational amplifier as a second input.
