Longitudinal RF Signal Processor
The series of FBE RF signal processors incorporates front-end and back-end electronics
for a longitudinal bunch-by-bunch feedback systems. The unites are designated FBE-NNNL where NNN specifies the RF frequency.
The front-end channel is designed for converting the BPM output (typically from a 4-to-1 combiner) to
the baseband signal which can be directly digitized by the iGp. Front-end channel detection frequencies are around 1.5 GHz (dependent on the RF frequency). A comb filter is used to lengthen beam signal and reduce front-end sensitivity to sampling clock drifts and jitter. The back-end channel upconverts the baseband kick signal to the kicker frequency for driving the power amplifier and the kicker. The FBE
interfaces to the iGp digital I/O port for control of front- and back-end attenuators and phase shifters.
