Frequently Asked Questions
What is the characteristic impedance and contact finish specification of the SMP-PL-P-GF-ST-TH2?
The SMP-PL-P-GF-ST-TH2 features a characteristic impedance of 50 ohms and uses gold-plated (10 microinch) brass contacts for the mating interface. The 50 ohm impedance ensures compatibility with standard RF coaxial transmission lines and components used in microwave signal chains. Gold plating provides low and stable contact resistance along with resistance to oxidation, which is critical for maintaining signal integrity in high-frequency applications up to several GHz.
How does the threaded coupling of the SMP-PL-P-GF-ST-TH2 benefit RF assemblies in high-vibration environments?
The threaded coupling mechanism of the SMP-PL-P-GF-ST-TH2 provides a mechanically locked RF mating interface that resists vibration-induced disconnection better than snap-on or push-on SMA connectors. This is especially important in aerospace, defense, and vehicular RF systems where mechanical shock and vibration loads are significant and intermittent contact can degrade 50 ohm signal continuity. The threaded mating also allows controlled torque application to ensure consistent contact force and impedance repeatability across connector matings.
What PCB mounting style does the SMP-PL-P-GF-ST-TH2 use and how does it affect mechanical reliability?
The SMP-PL-P-GF-ST-TH2 uses a through-hole (TH) mounting style, where connector pins pass through plated PCB vias and are soldered from the bottom side. Through-hole mounting provides significantly stronger mechanical attachment compared to surface-mount RF connectors, making it better suited for applications where cable pull forces or mating torque could otherwise lift pads or crack solder joints. This mounting style is preferred in test-and-measurement equipment and harsh-environment RF modules requiring long-term reliability.
Which RF systems and frequency bands is the SMP-PL-P-GF-ST-TH2 designed to serve?
SMP series connectors like the SMP-PL-P-GF-ST-TH2 are designed for compact microwave assemblies operating from DC up to approximately 40 GHz, making them suitable for 5G millimeter-wave modules, satellite communication bands (Ku/Ka), radar systems, and high-speed test equipment. The 50 ohm impedance and gold contact finish ensure low insertion loss and consistent return loss across the supported frequency range. They are a popular choice for board-to-board RF interconnects in densely packed microwave PCB stacks where SMA connectors are too large.
