Description

Current reference data for 122489: 50 Ohms · 11 GHz · Bulkhead - Rear Mount. The catalog currently lists the configuration as: Straight · Solder. Impedance is listed as 50 Ohms. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 11 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 Bulkhead - Rear Mount. If panel, bulkhead, or flange constraints matter, send the dimensions with the RFQ. The catalog also lists a sealing or protection value of _. Check that against the real environment requirement in RFQ. Use this page to shortlist before RFQ, not as the final sign-off.
