Overview
The SSMA connector features a 10-36 threaded coupling and is a miniaturized version of the SMA. It combines a compact design with wide frequency bandwidth and reliable mechanical performance. The male contact is sized to match the cable conductor, allowing it to serve as the mating pin for optimized VSWR, ensuring superior signal integrity in high-frequency applications such as radar systems, avionics, and navigation equipment,electronic warfare, military radios, and secure communication links .

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.
