    摘要: A feedforward amplifier system comprises a main amplifier and an auxiliary amplifier. An input signal including one carrier signal used as a first pilot signal, is supplied to a main amplifier to produce an amplified output signal. A second pilot signal is injected into the amplified output signal. The amplified output signal from the main amplifier is supplied to an output of the amplifier system through a delay line. In each of a first loop associated to the main amplifier and a second loop including the auxiliary amplifier, two control signals with pilot signal components arc produced, discrete Fourier transforms of the pilot signal components of the two control signals are calculated, and the amplitude and phase of the input signal of the main or auxiliary amplifiers are adjusted to values making the two Fourier transforms substantially equal to each other. Alternatively, the first pilot signal is produced by a generator and is injected into the input signal. With this alternative, the signal processing is unchanged but a bandpass filter is added at the system output to withdraw the first pilot signal.

    摘要: There is disclosed a connector and method for terminating a cable comprised twisted pairs of conductors. In one aspect of the invention the connector comprises a wire lead guide for arranging the twisted pairs of conductors and a plurality of piercing contacts which interconnect with respective ones of the twisted pairs of conductors when the wire guide is secured to the module. In a further aspect of the invention the wire lead guide ensures that the spacing between the conductors of a particular twisted pair is maintained, thereby improving the performance of the subsequent assembly.
