SMB Fakra Plug for Automotive RF — Code K Keying, 50 Ohm, 3 GHz
The PTFE dielectric maintains consistent impedance up to the 3 GHz maximum frequency, covering GPS, cellular, and satellite radio bands.
Why the 3 GHz Frequency Limit Matters vs. 6 GHz Siblings
The 2FA1-NKSP-PCBB6 is rated to 3 GHz, while the FA1-NCRP-PCB-8 (Code C), FA1-NDRP-PCB-8 (Code D), and FA1-NARP-PCB-8 (Code A) siblings are each rated to 6 GHz. That 3 GHz ceiling is the key selection gate: if your application requires the full 6 GHz bandwidth (e.g., 5G NR or dual-band Wi-Fi), step up to one of the 6 GHz-rated Fakra variants. For GPS /L5, 4G LTE, AM/FM, and SDARS, the 3 GHz ceiling leaves headroom. The Code K keying is unique to this variant — it physically prevents mating with a Code A, C, or D receptacle, so the keying code must match the harness-side connector.
