Bunch-by-bunch Front/Back End
The series of FBE-LT RF signal processors incorporates front-end and back-end electronics
for bunch-by-bunch feedback in three planes. The units are designated FBE-NNNLT where NNN specifies the RF frequency.
Three front-end channels are designed for converting BPM signals from a hybrid network to
baseband signals which can be directly digitized by the iGp/iGp12. Front-end channels are designed for detection frequencies around 1.5 GHz (dependent on the RF frequency) and use comb filters to lengthen beam signals and reduce front-end sensitivity to sampling clock drifts and jitter. The back-end channel upconverts the baseband longitudinal kick signal to the kicker frequency for driving the power amplifier and the kicker. The FBE-LT interfaces to the iGp/iGp12 digital I/O port for control of front- and back-end attenuators and phase shifters. The same interface is also used to read out unique FBE-LT ID, monitor its internal temperature, and control the cooling fan speed.
