Product details
Attenuators are used to reduce the power of a signal without causing distortion of its waveform. They are used in many test and measurement and communication applications.
Part number (MPN)
Impedance
50Ω
Frequency
0 GHz ... 18 GHz
Interface
SMA / jack (female)
Need a custom version from drawing?
We coordinate supplier-qualified RF connector and cable assembly sourcing from drawings, samples, or BOM. Typical production lead time is 3–6 weeks after drawing/spec review; feasibility, MOQ, and fit are confirmed by RFQ.
Before RFQ Clear inputs speed up review. ⌄
- • Share the reference MPN and source brand if it matters.
- • Add the BOM and volume split for production projects.
- • Attach the drawing or the key fit requirements.

Description
Current reference data for 85177147: SMA / jack (female) · 50Ω · 0 GHz ... 18 GHz. Impedance is listed as 50Ω. If that parameter is critical, confirm it again in RFQ. Frequency is listed as 0 GHz ... 18 GHz. The real operating limit still depends on the assembly, mating pair, and application context. 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.
