Overview
The MMCX (Micro-Miniature Coaxial) connector series is a compact version of the MCX, designed for applications where space is limited. It features a 50 ohm impedance and broadband performance from DC to 6 GHz. MMCX connectors offer secure, fast, and easy snap-on/snap-off coupling, simplifying installation and maintenance for applications: RF ablation, telemetry, and diagnostic tools,patient monitoring systems with wireless connectivity .Their smaller footprint compared to MCX makes them ideal for dense system layouts, and they are available in a wide range of configurations to suit various design needs. Like the MCX series, MMCX connectors comply with the European CECC 22000 standard, ensuring reliable performance and consistent quality across applications.

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 is the difference between RF connectors and coaxial connectors?
They are often used interchangeably. However: Coaxial connector refers to the physical design (shielded cylindrical form). RF connector emphasizes its use in radio-frequency applications. Most RF connectors are coaxial.
What is “reverse polarity” (RP-SMA, RP-TNC)?
Reverse polarity means the gender of the center pin is swapped while keeping the outer body style unchanged. It was introduced to comply with regulatory requirements in Wi-Fi devices and to prevent connection with standard SMA/TNC.
What’s the lifespan of an RF connector?
Connector durability is rated in mating cycles: General-purpose connectors (BNC, SMA): 500 cycles. Precision connectors (2.92 mm, 2.4 mm): 500 cycles or less. Rugged telecom connectors (N, 7/16 DIN): 500 cycles.
Can RF connectors be reused?
Yes, but performance degrades with wear. Precision connectors (used in test equipment) should be handled carefully—damage to threads or pins increases VSWR and insertion loss.
