FAKRA Cable High Performance

FAKRA is an automotive-grade RF interconnect system based on SMB geometry, keyed and color-coded to prevent cross-mating while maintaining 50 Ω impedance.

Every assembly is continuity-checked and vector-network-analyzed to 4 GHz (VSWR < 1.3), ensuring rock-solid GNSS, LTE, satellite-radio and ADAS signals.

Rated DC – 4 GHz with a nominal 50 Ω characteristic impedance; low-loss builds provide headroom up to 6 GHz.

Blue B (GPS), Bordeaux-violet C (cellular), Green E (satellite radio), Brown F (AM/FM) and universal Aqua Z.

Code Z is un-keyed (“universal”) for lab or retrofit work; Code C has a dedicated mechanical key and Bordeaux-violet jacket for cellular telematics modules.

Standard builds use RG-174 LL for flexibility; premium low-loss options (RTK031 / TFC-302 LL) cut insertion loss by ~40 %.

The RF pin mates electrically with SMB, but the keyed plastic housing blocks direct connection. Use our FAKRA-to-SMB adapters when cross-connecting lab gear.

GNSS antennas, LTE/5G telematics, satellite radio, HD-radio, Wi-Fi, rear-view cameras, LiDAR timing and V2X DSRC links.

Yes—they meet ISO 20860-1 electrical and SAE USCAR-17 mechanical-pull (≥ 90 N) and operate from -40 °C – +105 °C.

The secondary lock tab withstands > 100 N axial force; a violet eject-key tool releases it in tight dash cavities.

Absolutely—every lot is tested < 0.1 % Pb/Cd/Hg; compliance declarations ship with your invoice.

Yes—any length from 4 in (10 cm) to 50 ft (15 m), with optional heat-shrink ID, over-molding or braided PET sleeve (MOQ 100 pieces).

8 × OD (≈ 20 mm for RG-174); frequent flex at 25 mm radius passes 2 000-cycle vibration per USCAR-2.

≈ 1.5 dB @ 2 GHz on RG-174; ≈ 0.7 dB on low-loss RTK031—ideal for runs from roof antenna to telematics ECU.

Keep ≥ 100 mm from ignition coils or DC/DC converters, cross power cables at 90 °, and bond shields to chassis ground.

Yes—6 ft, 10 ft and 15 ft Z-to-Z or C-to-C extensions ship from stock.

Specify our UV-stabilized jacket and nickel-plated housings; IP67 caps are available for exposed antennas.

250 units with laser-etched logo and custom bag header.

Lifetime signal-integrity warranty plus a 30-day no-quibble return policy.

Press the side latch until it clicks, then pull straight—avoid twisting to protect the keyed shell.

FAKRA adds keyed plastic housing, higher pull-force, color coding and vibration resistance; SMA is lighter but lacks automotive safety locking.

ISO 9001 and IATF 16949 production; cable lots are serialized and traceable to SPC data.

Yes—low-loss assemblies keep IL < 2 dB across 5.925–7.125 GHz, making them 6 GHz-ready for in-car access points.
