Project Description
Project Specification:
document:RFFE-Specification-Document-v2.pdf
The RFFEv1 is an analog Front-End that has four RF inputs and provides
four calibration schemes with an improved performance in terms of
linearity and long term stability.
Calibration schemes:
On-line pilot-tone: Couple a reference RF signal to the beam signal into
the four RF chains at the same time.
Off-line pilot-tone: Couple a reference signal to each of the RF
channels, one by one, turning off the beam signal.
Temperature controller: The RFFEv1 has 14 RTD's and distributed heaters
on the board.
Crossbar switching: Provides a crossbar scheme to swap the channels 2x2.
