RF and microwave on-wafer probes: Long-lasting, rugged, ACP series

The Air Coplanar Probe is a rugged microwave probe with a compliant tip for accurate, repeatable measurements on-wafer. It features excellent probe-tip visibility and the lowest loss available. Available as both single and dual, the ACP probe combines outstanding electrical performance with precise probe mechanics and is todays most widely used microwave probe available.
