摘要： An apparatus and method for continuously shifting the phase of an input signal includes a quadrature hybrid having an input/output port for receiving an input radio frequency (RF) signal and outputting a phase shifted RF signal. An analog shifting unit is connected to the quadrature hybrid for performing an intermediate phase shift on the input RF signal. An additional analog shifting unit is connected to an isolation port of the quadrature hybrid to receive an intermediate output signal based on the intermediate phase shift, and shifting a phase of the intermediate output signal to produce an intermediate input signal. The analog shifting unit performs a final phase shift of the intermediate input signal and the final phase shifted intermediate input signal is output, at the input/output port, as the phase shifted RF signal.

摘要： 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.

摘要： 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.
