In the world of radio frequency (RF) communications, the quality of your cable assembly can be the weakest link in your system. This 1.13 RF Coaxial Cable Assembly, featuring an SMA Male to SMA Female connector pair, is engineered to provide robust, low-loss connectivity in a compact and flexible form factor. Designed for precision and durability, this pigtail cable is the go-to solution for extending, adapting, or relocating antennas and RF modules across a multitude of devices. Its slender 1.13 mm diameter allows for easy routing through tight enclosures and crowded circuit boards, making it indispensable for modern miniaturized electronics.
Unparalleled Performance and Technical Specifications
This cable is not merely a connector; it is a vital component optimized for high-frequency signal transfer. The core technical prowess lies in its construction.
Cable Type: 1.13 Coaxial CableThe ultra-fine 1.13 cable is specifically chosen for applications where space is at a premium and a high degree of flexibility is required. It offers a good balance of signal shielding and minimal footprint. While its attenuation is higher than thicker cables, it excels in short-run applications typical for internal device wiring.
Connectors: SMA Male to SMA FemaleThe SMA (SubMiniature Version A) connectors are the industry standard for high-frequency applications up to 18 GHz, renowned for their reliable threaded coupling mechanism which ensures a secure, vibration-resistant connection.
The SMA Male connector features a center pin and an internal thread, typically used to connect to a device's chassis or antenna port.
The SMA Female connector features a center sleeve and an external thread, commonly used for bulkheads or extending an existing connection. This configuration makes the pigtail ideal for routing an internal connection to an external chassis mount, allowing an external antenna to be attached.
Material and Construction ExcellenceDurability and signal integrity are paramount. The inner conductor is typically silver-plated copper or copper-clad steel, chosen for excellent conductivity. The dielectric insulator is a high-grade PTFE (Polytetrafluoroethylene), which is crucial for maintaining a stable impedance of 50 Ohms across the operating frequency range, minimizing signal reflection (return loss). The outer jacket is made from robust, high-temperature-resistant material, ensuring longevity even in challenging operational environments. Every cable is factory-tested to ensure low Voltage Standing Wave Ratio (VSWR), guaranteeing minimal signal loss and maximum power transfer.
Extensive Use Cases and System Integration Applications
The versatility of the 1.13 RF Coaxial Cable is what makes it a staple component in various technological sectors. It bridges critical RF components, enabling sophisticated communication architectures.
Wireless Networking and IoT (Internet of Things)
Antenna Extension/Relocation: Used internally within laptops, tablets, access points, and routers to connect the Wi-Fi or Bluetooth module to an internal or external antenna mount, allowing for optimal antenna placement for maximum signal strength.
Miniaturized Device Integration: Critical for small form-factor IoT devices, sensors, and embedded systems (like Raspberry Pi or Arduino shields) where space constraints dictate the use of the slimmest cable possible to link the transceiver to the antenna.
Testing, Measurement, and Prototyping
Test Fixtures and Jigs: Essential for connecting high-frequency test equipment (like Spectrum Analyzers or Network Analyzers) to devices under test (DUT) with SMA ports, often used in conjunction with adapters or specialized test boards.
SDR (Software Defined Radio) Applications: Allows hobbyists and professionals to connect their SDR dongles or receivers to different types of external antennas, experimenting with various frequencies without stressing the main device connector.
Communication Systems and Telemetry
GPS/GNSS Systems: Employed in vehicle tracking and navigation units to connect the GPS receiver module to the external, roof-mounted antenna. The flexibility of the 1.13 cable facilitates neat installation within a vehicle's dashboard or paneling.
Drone and UAV (Unmanned Aerial Vehicle) Technology: Used for video transmission (VTX/VRX) and control signal lines (e.g., 5.8 GHz or 2.4 GHz systems). Its light weight minimizes the overall payload, a crucial factor in drone design.
OEM Integration and Manufacturing
Mass Production Devices: Due to its consistent 50 Ohm impedance and high-reliability connectors, it is a perfect choice for original equipment manufacturers (OEMs) looking for a reliable, repeatable, and cost-effective internal wiring solution for their high-volume consumer electronics.
Conclusion: The Backbone of Reliable RF Communication
The 1.13 RF Coaxial Cable with SMA Male to SMA Female connectors represents a critical intersection of miniaturization and high-frequency performance.
