Overview
The SSMB connector is a compact RF coaxial connector designed for high-frequency applications where space is limited. It features a snap-on mating mechanism for fast, reliable connections without the need for tools. With a 50 ohm impedance, SSMB connectors support broadband frequencies up to 12.4 GHz, delivering low reflection and excellent signal integrity. Their miniature size makes them ideal for dense layouts in test equipment, telecommunications, aerospace, electronic warfare, military radios, and secure communication links,missile guidance, drones, and satellite payload systems and military systems. Available in both male and female configurations, SSMB connectors provide durable, repeatable, and high-performance connections in demanding, space-constrained designs.

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.

Are RF connectors weatherproof?
Some RF connectors are designed with gaskets and sealing (e.g., N-type, 4.3-10) for outdoor telecom, antennas, and harsh environments. Indoor lab connectors (e.g., SMA, BNC) are usually not weatherproof unless specified.
What’s the difference between male and female RF connectors?
Male: Has a center pin and usually an outer thread or bayonet. Female: Has a receptacle (socket) for the center pin and matching thread. Some connectors (like SMA) can be confusing because “reverse polarity” (RP-SMA) swaps pin/socket configuration.
What is VSWR, and why does it matter?
VSWR (Voltage Standing Wave Ratio) indicates signal reflection. Ideal: 1.0 (perfect match). Lower VSWR means less signal loss and distortion.
What are typical applications of RF connectors?
Telecom (5G, LTE, satellite) Aerospace & defense (radar, avionics, secure comms) Test & measurement (network/spectrum analyzers) Broadcast & video distribution Automotive radar and IoT devices Medical imaging & equipment
