Overview
SSMC connectors are designed for space-constrained applications that require the reliability of a threaded coupling mechanism. They are well-suited for use with semi-rigid or miniature flexible cables, providing secure, high-performance connections in demanding environments. Supporting frequencies up to 12.4 GHz, SSMC connectors deliver consistent signal integrity while maintaining a compact footprint, making them an excellent choice for high-frequency designs where space and durability are critical for applications studio equipment, satellite uplink/downlink stations,cable TV distribution and headend systems .

FAQ
Sample Delivery Time
Regular models require 15 days, while some complex connectors require 25 days.
Sample Fee
Most RF connectors are CNC-machined parts and do not require mold-making.
However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.
This fee will be refunded after a 5K bulk order.
Guarantee
Brass RF connectors come with a one-year warranty.
Stainless steel connectors come with a three-year warranty.
The lifespan also depends on the contact material beryllium contacts offer better durability.

What’s the difference between threaded, bayonet, and push-on RF connectors?
Threaded (SMA, N, TNC): Secure, vibration-resistant. Bayonet (BNC): Quick connect/disconnect. Push-on (MCX, SMP): Ultra-fast, compact, used in high-density modules.
Are RF connectors interchangeable between brands?
Yes, if they follow the same standard (e.g., SMA-to-SMA). However, tolerances, plating, and dielectric quality vary — mixing low-quality and precision connectors can damage equipment.
How do environmental conditions affect RF connectors?
Temperature extremes can cause expansion/shrinkage and change performance. Humidity and salt spray may cause corrosion (use stainless steel or weatherproof designs). Vibration may loosen bayonet types — use threaded connectors in harsh environments.
Can RF connectors be adapted from one type to another?
Yes, RF adapters (e.g., SMA-to-N, BNC-to-TNC) exist. But:Each adapter adds insertion loss and possible VSWR increase.Avoid stacking multiple adapters in sensitive applications.
