Description
Current reference data for 142-0791-811: 50 Ohms · 18 GHz · PCB Mount. The catalog currently lists the configuration as: End Launch · Solder. Impedance is listed as 50 Ohms. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 18 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 PCB Mount. If panel, bulkhead, or flange constraints matter, send the dimensions with the RFQ. Material is listed as Beryllium Copper. That is useful for review, but it does not replace full project stack-up confirmation. Use this page to shortlist before RFQ, not as the final sign-off.
Use this page to shortlist before RFQ. MOQ 200+ custom production is confirmed after drawing/spec/BOM review.
