Description

Current reference data for 22645979: SK · 50 Ω · 40 GHz. Impedance is listed as 50 Ω. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 40 GHz. The real operating limit still depends on the assembly, mating pair, and application context. For higher-frequency projects, include the drawing, cable path, and critical requirements in the first RFQ. Mounting is listed as square flange / 12.7 X 12.7. If panel, bulkhead, or flange constraints matter, send the dimensions with the RFQ. Use this page to shortlist before RFQ, not as the final sign-off.

Use this page to shortlist before RFQ. MOQ 200+ custom production and supply path are confirmed after drawing/spec/BOM review; no spot stock is assumed.
