Description

The LWC-433-MM-03 is a purpose-built RF coaxial cable assembly for developers and integrators working in the 433MHz ISM band. Its RG58 construction offers a practical solution for extending connections between Sub-1GHz transceiver modules—such as LoRa, ASK/OOK, or FSK types—and their corresponding antennas, or for linking test equipment. The cable maintains a 50-ohm characteristic impedance, critical for minimizing signal reflections and ensuring maximum power transfer in RF circuits.

With a specified VSWR of less than 2.0 across its operational bandwidth, this cable helps preserve signal strength and integrity. The 3-meter length provides ample flexibility for installation within enclosures, across prototypes, or in deployed sensor nodes. The SMA male connectors are a standard in the industry, offering a secure and reliable interface for a wide range of commercial and hobbyist RF hardware.

Key Features

  • Precision-engineered for the 433 MHz ISM band (+/- 10MHz).
  • 3-meter RG58 coaxial cable offering a good balance between flexibility and low signal attenuation.
  • Dual SMA male (plug) connectors for universal compatibility with RF ports.
  • 50-ohm impedance matched for optimal RF performance and minimal reflection.
  • High power handling capability of up to 10 Watts.
  • Low VSWR (less than 2.0) ensures efficient power transfer from source to load.
  • Linear polarization support for use with standard dipole or whip antennas.
  • Compact and lightweight design for easy integration into projects and enclosures.

Applications

  • Extending antenna connections for 433MHz LoRaWAN nodes and gateways.
  • Linking Sub-1GHz RF modules (FSK, OOK) to external antennas in IoT sensor networks.
  • Connecting RF test equipment (signal generators, analyzers) to devices under test.
  • Wiring within wireless security systems, garage door openers, or weather stations operating at 433MHz.
  • Providing a flexible feed line for prototype and development boards using 433MHz transceivers.

Frequently Asked Questions

What devices is this 433MHz SMA cable compatible with?

This cable is compatible with any RF device featuring a female SMA jack port operating around 433MHz. This includes popular LoRa modules (like RFM95/96), FSK transceivers, wireless sensor nodes, and many IoT development boards that have an external antenna connector. Ensure your device's port is a standard female SMA (socket) to accept the male plug connectors on this cable.

Can I use this cable for frequencies other than 433MHz?

While optimized for 433MHz (+/-10MHz), RG58 cable can be used for other VHF/UHF frequencies, but performance will vary. Signal loss (attenuation) increases with frequency. It may work for shorter runs at 868MHz or 915MHz, but for optimal performance at those bands, a cable with lower loss per meter (like RG174 or LMR-200) is recommended. Always check the cable's datasheet for attenuation specs at your target frequency.

How do I ensure a good connection and maintain signal integrity?

First, hand-tighten the SMA connectors firmly but avoid over-tightening with a wrench, which can damage the threads. Ensure the cable is not sharply bent or kinked, as this can deform the internal conductor and dielectric, altering impedance and causing signal loss. Route the cable away from sources of strong electromagnetic interference (EMI) like power supplies or motor drivers to maintain signal integrity in your application.
