Overview
The MCX connector series offers 50 ohm and 75 ohm options with broadband performance from DC up to 6 GHz. Designed for quick, reliable connections, MCX connectors feature a secure snap-on/snap-off coupling mechanism that simplifies assembly and disassembly. Introduced in the 1980s, these compact connectors provide a space-saving solution for high-frequency applications while maintaining signal integrity. MCX connectors comply with the European CECC 22220 standard, ensuring quality and consistency across applications. Ideal for RF, microwave, railway communications and signaling systems,in-vehicle infotainment and connectivity systems and data transmission systems, the MCX series combines durability, ease of use, and versatile electrical performance in a small form factor.

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.
ROHS & REACH Compliance
Our products fully comply with ROHS & REACH regulations.

What is impedance, and why is 50 Ω or 75 Ω important?
Impedance matching prevents signal reflection and power loss. 50 Ω: Standard for RF communication, test equipment, aerospace, defense. 75 Ω: Standard for broadcast, video, and cable TV applications.
What materials are RF connectors made of?
Body: Brass, stainless steel, or beryllium copper (with nickel, gold, or silver plating). Insulator: PTFE, PE, or advanced low-loss dielectrics. Contacts: Gold-plated brass or beryllium copper for low resistance and 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.
