| *TUNGSTEN TIPS* DP style shown. This RF probe head sets new standards in microwave probing performance. Using low loss coaxial techniques, the model 40A achieves an insertion loss of less than 0.8 dB and a return loss of greater than 18 dB through 40 GHz. With its individually spring loaded Tungsten tips this probe head provides reliable contacts, even when probing non-planar structures. This reliable low resistance contact is one of the keys to providing highly repeatable measurements. Direct viewing of probe tips allows accurate positioning. Any pitch (tip spacing) from 50 to 1250 microns may be specified. Pitches greater than 1250 microns are available on special order. Head can be configured with Ground-Signal-Ground (G,S,G), Ground-Signal (G,S), or Signal-Ground (S,G) tip footprints. Connection is through a female K connector (2.9mm) which is 3.5mm connector compatible. |
