摘要： In an embodiment, a communication circuit includes a frequency-shifting circuit coupled to a signal path, which is configured to carry, during a first period, an information signal having a first frequency. The frequency-shifting circuit is configured to receive a control signal, to shift the first frequency of the information signal by a second frequency in response to the control signal having a first control value, and to shift a third frequency of an interference signal on the signal path during a second period by a fourth frequency in response to the control signal having a second control value. For example, such a communication signal can be configured to shift the frequencies of an interference signal generated by the signal path out of the passband of an adjacent signal path to reduce the interference superimposed on a signal carried by the adjacent signal path.

摘要： In an embodiment, a signal repeater includes a master unit and a remote unit that are optically coupled to one another by, e.g ., an optical fiber. The master unit includes master-unit circuitry configured to receive an input electrical signal from a satellite-signal receive antenna, and to convert the input electrical signal into an optical signal. And the remote unit includes remote-unit circuitry configured to convert the optical signal into an intermediate electrical signal, to amplify the intermediate electrical signal to generate an output electrical signal, and to couple the output electrical signal to a retransmission antenna. Because an optical channel, such as an optical fiber, typically attenuates an optical signal significantly less per unit of distance than a coaxial cable attenuates an electrical signal, such a signal repeater allows a satellite receive antenna to be located at a significant distance from a retransmit antenna.

摘要： A telecommunications system may be configured to improve linearity and blocking. In some aspects, the telecommunications system may include a duplexer for coupling a common port to a receive path and a transmit path. A distributed low- noise amplifier having two or more separate active devices (e.g., amplifiers) may be positioned in the receive path. A filtering element (e.g., a band-pass filter) may be positioned between the two or more separate active devices. A signal may be routed by the duplexer through the distributed low-noise amplifier. The filtering element may attenuate transmit signals in the receive path.

The telecommunications system includes a phase correlation measurement unit that can be between a sectorized antenna sub-system and a remotely located RF source site. The phase correlation measurement unit can be coupled to the RF source site over at least one feed line. The phase correlation measurement unit can ouptut signals for controlling a phase shifter at the RF source site for phase shifting downlink signals and for causing operation of the sectorized antenna sub-system as an omnidirectional antenna sub-system. In a sectorized operation mode, the phase correlation measurement unit and the phase shifter can be inactivated.
