Key Features
- Threaded SMA coupling mechanism ensures secure mating with standard SMA cables and maintains 50 Ω characteristic impedance up to 18 GHz
- Gold-plated mating and termination contacts minimize contact resistance and protect against oxidation for long-term signal integrity
- Surface-mount PCB footprint with high-temperature rating supports reflow soldering and simplifies automated assembly
- Compact right-angle PCB-mount form factor allows horizontal RF cable routing while keeping the RF feed point close to the board edge
Applications
The PCB.SMAFSTJ.A.HT is used in wireless communication modules, RF test equipment, and IoT gateway designs where a robust SMA connection point is required directly on the PCB. Its high-temperature tolerance makes it suitable for automotive telematics units, industrial wireless sensors, and measurement instruments that undergo reflow soldering at temperatures up to 260°C. The threaded SMA interface is also favored in antenna evaluation boards and software-defined radio platforms where a stable 50 Ω coaxial connection is critical for accurate RF measurements.

Frequently Asked Questions
Up to what frequency can the PCB.SMAFSTJ.A.HT SMA connector operate reliably?
The PCB.SMAFSTJ.A.HT SMA connector supports operation from DC to 18 GHz with a characteristic impedance of 50 Ω. This frequency range makes it compatible with Wi-Fi (2.4 GHz and 5 GHz), LTE (up to 3.8 GHz), GPS (1.575 GHz), and other sub-18 GHz RF standards used in wireless communication and test-and-measurement equipment.
How does the threaded coupling on the PCB.SMAFSTJ.A.HT improve performance in vibration-prone environments?
The SMA threaded coupling (28 threads per inch) mechanically locks the mated cable connector in place, preventing accidental disconnection in environments with vibration or shock. This is critical in automotive, industrial, and aerospace applications where vibration can cause intermodulation or signal dropout in connectors without positive locking. The gold-plated contacts further ensure stable contact resistance below 5 mΩ through thousands of mating cycles.
What PCB soldering process is compatible with the PCB.SMAFSTJ.A.HT, and what temperature does it support?
The PCB.SMAFSTJ.A.HT carries a JESD-609 code of e4, indicating it is RoHS-compliant and compatible with lead-free reflow soldering processes at peak temperatures up to 260°C for 30 seconds. This makes it suitable for standard SMT assembly lines and eliminates the need for manual soldering, reducing assembly cost and improving joint consistency on high-volume production runs.
When would an engineer choose PCB.SMAFSTJ.A.HT over an edge-launch or through-hole SMA connector?
Engineers select the PCB.SMAFSTJ.A.HT surface-mount version when minimizing PCB layer transitions and solder joint inductance is important, particularly at frequencies above 6 GHz. Unlike through-hole variants that add via inductance to the RF signal path, the SMT footprint of the PCB.SMAFSTJ.A.HT connects directly to the top-layer trace, maintaining the 50 Ω impedance transition and reducing insertion loss by approximately 0.1 dB to 0.3 dB compared to through-hole alternatives at 10 GHz.
