Description

The LWC-433-MM-03 is a professional-grade 5-meter RF coaxial cable assembly designed for reliable signal transmission in the 433 MHz Industrial, Scientific, and Medical (ISM) band. Utilizing RG58 coaxial cable with SMA male connectors on both ends, it provides a robust physical link between RF transceivers, antennas, and IoT devices. Its 50-ohm impedance ensures compatibility with standard RF systems, while the low VSWR (<2.0) guarantees efficient power transfer with minimal signal loss over its length.

This cable is constructed for durability and consistent performance in wireless communication setups, including LoRaWAN networks, sub-1GHz sensor nodes, and industrial telemetry. The linear polarization and 3.5 dBi gain specification indicate its pairing with compatible omnidirectional or dipole antennas to extend operational range. With a power handling capability of 10 watts, it is suitable for both low-power IoT endpoints and higher-power transmitter applications, making it a versatile component for system integrators and RF engineers.

Key Features

  • Extended 5-Meter Reach: Enables flexible placement of antennas away from RF modules for optimal signal propagation and reduced interference.
  • Low-Loss RG58 Coaxial Construction: Provides effective shielding against electromagnetic interference (EMI) for clean signal integrity over distance.
  • Precision SMA Male Connectors: Gold-plated contacts ensure reliable, low-resistance connections and repeated mating cycles without degradation.
  • 433 MHz ±10MHz Tuned: Specifically engineered for optimal performance in the popular 433MHz ISM band, covering common LoRa and wireless protocol frequencies.
  • Robust Power Handling: Capable of supporting transmission power up to 10W, accommodating both sensitive receivers and powerful transmitters.
  • Standard 50-Ohm Impedance: Matches the impedance of most commercial RF equipment, preventing standing waves and signal reflection.

Applications

  • LoRa & LoRaWAN Network Deployment: Extend antenna placement for gateways and nodes operating in the 433MHz region to improve coverage.
  • Sub-1GHz Wireless Sensor Networks: Connect 433MHz RF modules (e.g., SI4432, CC1101) to external antennas for environmental monitoring and industrial IoT.
  • Remote Control & Telemetry Systems: Facilitate connections for RC models, drone control links, and long-range telemetry data transmission.
  • Amateur Radio & DIY RF Projects: Serve as a reliable feed line for ham radio setups, antenna analyzers, and custom transmitter builds.

Frequently Asked Questions

What devices is this SMA male-to-male cable compatible with?

This cable is compatible with any RF device featuring a standard SMA female port, including 433MHz LoRa modules (SX1276/SX1278), sub-1GHz transceivers, wireless gateway antennas, and amateur radio equipment. Ensure your device operates within the 433MHz ±10MHz range and uses 50-ohm impedance for optimal performance. Avoid using it with RP-SMA or other connector types without a proper gender-changing adapter.

How do I calculate the signal loss for this 5-meter RG58 cable at 433MHz?

Signal loss depends on the cable's attenuation per meter, typically around 0.3 dB/m for RG58 at 433MHz. For a 5-meter run, expect approximately 1.5 dB of insertion loss. This is acceptable for most IoT applications. For critical low-power links, use a shorter cable or a lower-loss type like LMR-200. Always position your antenna as high and clear as possible to offset cable losses.

Can I use this cable for frequencies other than 433MHz, like 868MHz or 2.4GHz?

While it is tuned for 433MHz, it may function at 868MHz or 2.4GHz with increased attenuation and higher VSWR, degrading performance. For 868MHz LoRa or 2.4GHz Wi-Fi/Bluetooth, use a cable specifically rated for those higher frequencies. Mismatched cables can cause significant signal loss and potential damage to sensitive RF components due to reflected power.
