Fakra SMB Plug for RF Signal Paths
The Amphenol RF FA1-NDRP-PCB-8 is a 1-port Fakra SMB plug with Code D keying, designed for 50 Ohm RF systems up to 6 GHz. It comes as a two-piece assembly — the connector body and the housing are both included in the box. The locking ramp fastening gives it vibration resistance, which matters in automotive or mobile equipment where the cable sees movement. The through-hole right-angle mounting puts the plug parallel to the board, saving height in a tight enclosure.
What the Key Specs Mean for Your RF Link
The 6 GHz max frequency covers common bands like GPS, Wi-Fi, and cellular, but not mmWave. Insertion loss is 0.3 dB, which is low enough that it won't eat your link budget in a short cable run.
Code D vs Code C — Which Keying Fits Your Harness?
The FA1-NDRP-PCB-8 uses Code D keying (violet/claret housing). The keying prevents mating a Code D plug into a Code C jack. If your harness specifies Code C, the FA1-NCRP-PCB-8 is the drop-in; if it's Code D, this is the one. No other functional difference between them.
