Abstract :
In order to overcome range limitations, the existing Beam Position Monitor (BPM) receiver was modified, extending the dynamic range from 35 dB to 60 dB. The modifications include the insertion of an RF PIN attenuator, RF amplifier, and control circuitry in line with the RF link to add an extra 25 dB to the existing AGC loop. This standalone 25 dB RF gain control stage is integrated into the present system without any change to the existing receiver
