A 20 GHz Landing Probe Design Based on Pogo-pins

A landing probe design is proposed in this paper based on pogo-pins. Landing probes are usually used to obtain TDR and S-parameters of the device under test (DUT) so that the performance of the DUT can be evaluated. This design has two major advantages. First, it is durable. Second, it can be easily integrated into automated testing systems. The designed probe works well up to 20 GHz, which is validated by measurement.
