Multi-tone RFSoC driver for an AOM
Team member: Mani Aarthy
Objective
Design, implement, and characterise a multi-tone RF synthesiser on an RFSoC platform capable of driving AODs or AOMs used for trapped-ion and neutral-atom qubit control.
The synthesiser must support two operating modes on the same hardware:
1) Ion mode — few tones (1–4) per channel, optimised for phase purity and deterministic inter-tone phase relationships. 2) Atom mode — many tones (32–64) per channel, optimised for intermodulation suppression and linear frequency chirping.
The FPGA prototype serves two purposes: it is a usable instrument in its own right, and it is the architectural and algorithmic testbench for a subsequent ASIC implementation depending on the outcome
