摘要： Method and apparatus are provided for compensation of an RF link between a transmitter and amplifier of a communication system. The apparatus comprises a signal source coupled to the transmitter for providing an RF test signal of a first magnitude to the RF link, a test signal measuring apparatus at the RF input of the amplifier for measuring a second magnitude of the test signal reaching the RF input of the amplifier through the RF link, and an electronically adjustable attenuator serially coupled with the RF link and responsive to differences between the first and second magnitudes so as to provide attenuation in an RF communication signal passing into the amplifier from the RF link such that the sum of RF signal loss in the link and the attenuator has a predetermined value.
