Description

Current reference data for 7029-3821: 50 ohms · 18 GHz · Straight. 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 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. If mounting is missing here, confirm it from the drawing or mating requirement. 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.
