SMB Fakra Plug for RF Signal Paths
The FA1-NISP-PCB-2: It uses a through-hole solder termination for the centre contact and shield, with a locking ramp fastening that provides positive retention in vibration-prone environments — typical for automotive antenna modules, telematics, and infotainment head units where the Fakra interface is the standard.
Impedance and Frequency Ceiling
The 4 GHz max frequency covers GPS, cellular, and Wi-Fi bands. For a Fakra plug, 4 GHz is the typical upper limit of the SMB interface; the locking ramp adds mechanical security that the standard SMB push-on lacks, at the cost of a slightly higher disconnect force.
Mating Cycles and Field Service
Rated for 100 mating cycles, which is standard for a field-serviceable RF connector in automotive or telecom gear — enough for initial assembly and a few service disconnects over the product life. The gold-on-gold contact interface (gold body finish, gold-plated centre contact) keeps contact resistance stable across those cycles; tin-plated contacts would fret and degrade the RF signal after far fewer mates.
