High-current switching under cryogenic conditions
The Apollo baseband switch covers the lines RF switches aren't built for: high-current, low-frequency paths for flux biasing and DC characterisation. With ultra-low on-resistance and near-zero dissipation, it routes currents at millikelvin without loading your thermal budget, on the same control bus as the rest of the Apollo family.
