QFilter is a compact solution for advanced multi-stage low-pass filtering designed to reject noise and reach millikelvin electron temperatures. It is available in three standard configurations supporting 24 or 48 lines:
– 24 lines, 1 RC + 1 RF board with a 6-inch jumper cable (standard, left figure)
– 48 lines with stacked dual RC and dual RF QFilters using two 6-inch jumper cables (top right)
– 48 lines with piggy-tailed dual RC and dual RF QFilters removing the need for jumper cables (bottom right)
Individual RC filter lines (1700Ω) can be shortened upon request, allowing for higher signal currents e.g. used for current biasing flux lines. 12-inch jumper cables are also available. Both options have the same price as the standard configurations. Please contact us directly for these requests.
