Detailed Introduction to Component CA100-NM-MMCX-12

Creation Date

CA100-NM-MMCX-12 is a radio frequency (RF) coaxial cable assembly developed and produced by Laird Technologies IAS. It is mainly used for the transmission and connection of RF signals in various electronic devices. With its standardized design and reliable performance, it is widely applied in various scenarios requiring miniaturized and low-loss signal transmission. Its alternative name includes 994-1005, which facilitates identification in procurement and inventory management.

I. Core Basic Information

This component belongs to the category of coaxial cable assemblies, with its core positioning being to realize signal transfer and transmission between RF devices of different interface types. The overall design complies with industrial-grade standards, balancing practicality and compatibility. Its standard packaging specification is 1 piece per package, suitable for small-batch trial and bulk procurement scenarios. Mainstream distributors in the market have it in stock, mostly brand-new imported original products, ensuring stable and reliable use.

As a dedicated RF cable assembly, CA100-NM-MMCX-12 can be directly used without additional complex accessories, which can effectively reduce signal loss in the equipment connection link, improve overall transmission efficiency, and is one of the indispensable basic connection components in RF systems.


II. Key Specifications and Parameters

Parameters are the core basis for component selection and application. The key parameters of CA100-NM-MMCX-12 are all standardized and calibrated, as follows (data source: official specification sheet and public market information):

  • Connector Specification: Adopts a male-to-male dual-joint design. The interface types at both ends are N-type male plug (first connector) and MMCX right-angle male plug (second connector), which can flexibly adapt to RF devices with different interfaces. The right-angle design is more suitable for narrow installation spaces.
  • Cable Parameters: Equipped with LMR 100 coaxial cable, which has the characteristics of good flexibility and low loss, suitable for efficient transmission of RF signals; the cable length is 12.0 inches (about 304.8mm), and some actual measurement data show that the length is about 310mm, which is a common specification for short-distance transmission. It can be flexibly arranged according to equipment installation needs to avoid signal interference caused by cable redundancy.
  • Core Performance: It has shielding characteristics, which can effectively block external electromagnetic interference (EMI) and RF leakage, ensuring the purity of transmitted signals; since the official has not clearly marked the impedance and maximum frequency parameters, referring to the same series of models (such as CA100-NFB-MMCX-12), its impedance is likely to be 50Ω (general standard for RF devices), and the frequency range can cover 700MHz to 5.82GHz, which can meet the needs of most medium and high-frequency RF signal transmission.
  • Environmental Adaptability: Combined with the general characteristics of MMCX interface, this assembly can adapt to the operating temperature range of -55℃ to +165℃, and can withstand harsh environments such as vibration, thermal shock and salt spray (referring to the general environmental standard of MMCX interface), adapting to the use needs of industrial, consumer electronics and other scenarios, with strong mechanical stability.

III. Product Features and Advantages

CA100-NM-MMCX-12 combines the advantages of LMR 100 cable and MMCX/N-type interface, and has obvious characteristics in performance and application scenarios, as follows:

  • Excellent Shielding Performance: With built-in shielding design, it can effectively suppress external electromagnetic interference and reduce its own RF signal leakage, ensuring the stability and accuracy of signal transmission. It is especially suitable for use in equipment with complex electromagnetic environments, such as communication base stations and test instruments.
  • Flexible and Convenient Installation: The MMCX right-angle male plug adopts a miniaturized design with small volume, which can adapt to the installation needs of dense electronic equipment; the cable is flexible, can be flexibly bent and arranged in narrow spaces, and does not require complex installation tools, with convenient plugging and unplugging, improving equipment assembly efficiency.
  • Strong Compatibility: N-type interface is a common standard interface in RF devices, and MMCX interface is widely used in miniaturized RF modules. The combination of the two enables this assembly to be compatible with various brands and types of RF devices, with strong versatility, reducing selection and replacement costs, and facilitating later maintenance and upgrading.
  • High Reliability: As a standardized product of Laird Technologies IAS, the assembly is made of high-quality materials (referring to general materials of MMCX interface: contacts are gold-plated brass, insulators are polytetrafluoroethylene, and shells are passivated stainless steel or gold-plated brass), with high mechanical strength, long plugging life, stable long-term operation, and reduced equipment failure probability.

IV. Applicable Application Scenarios

Based on its performance characteristics and specifications, CA100-NM-MMCX-12 is mainly used in scenarios requiring short-distance and low-loss RF signal transmission, especially suitable for miniaturized and dense equipment, including:

  • Consumer Electronics Field: Small wireless communication devices, GPS receivers, Bluetooth modules, WiFi devices, etc., used for the transfer of RF signals inside the equipment. With its miniaturized design and low-loss characteristics, it ensures the stable transmission of wireless signals.
  • Test and Measurement Field: Supporting connection of RF test instruments, signal generators, oscilloscopes and other equipment, used for the transmission and transfer of test signals. The shielding design can ensure the accuracy of test data and avoid test errors caused by interference.
  • Industrial Communication Field: Small RF modules, industrial wireless sensors, short-distance communication equipment, etc., adapting to the harsh conditions of industrial environments, can work stably for a long time, ensuring the continuity of industrial communication; at the same time, it can be used for signal connection of base station auxiliary equipment.
  • Other Scenarios: Medical electronic equipment (adapted for non-magnetic version), small aerospace RF components, etc., with its high reliability and compatibility, meeting the signal transmission needs of various special scenarios.
