MULTISTAGE RECEIVER SYSTEM |
摘要 |
A receiver system with controllable attenuators and a component with a limited input range, arranged to receive as its input signal the output signal from the attenuators. The receiver system also comprises a compensation circuit which varies the level of the output signal of the component and a control loop which monitors the component and controls at least one attenuator to be active or inactive so that the level of the signal to the component is within the input range, and controls the compensation circuit to keep the output signal of the component constant. The control of the compensation circuit and attenuators between the component and said at least one attenuator is carried out in synchronicity with the propagation of the received signal through the attenuator chain from said at least one attenuator.
