1.85 mm Female Four-Hole Solderless Panel-Mount RF Connector, DC–67 GHz
P/N: VST-CPM185F-04
– DC–67 GHz frequency range
– 1.85 mm female interface
– VSWR ≤1.45
– Four-hole flange mount
– Ø0.23 mm / Ø0.30 mm rear-pin options
Engineering Note
VST-CPM185F-04 brings a 1.85 mm female port to the wall of a 67 GHz test fixture or RF module without a permanent front-side cable. The four-hole flange fixes the connector reference plane, while the selectable Ø0.23 mm and Ø0.30 mm rear pin diameters let the launch be matched to the internal conductor geometry. The 11.3 mm body length and 9.5 mm × 6.35 mm mounting pitch are primary constraints for enclosure and substrate alignment.
