Description

The LWC-GSM-MM-03 is a dedicated RF coaxial cable assembly engineered for cellular communication systems. Its RG58 cable core and SMA male connectors provide a reliable, impedance-matched link between GSM/GPRS/3G modems and their corresponding external antennas, crucial for maintaining signal integrity over the 3-meter distance.

Built with a 50-ohm characteristic impedance and a VSWR under 2.0, this cable minimizes signal loss and reflection across the primary GSM frequency ranges. The linear polarization and broad horizontal beamwidth make it suitable for various mounting scenarios in IoT deployments, asset tracking, and remote telemetry applications requiring stable cellular connectivity.

Key Features

  • Dual-band coverage for standard GSM 900MHz and DCS/3G 1800-2100MHz frequency ranges.
  • High-quality RG58 coaxial construction ensures durability and consistent signal transmission.
  • Male SMA plug connectors provide a secure, screw-on interface compatible with standard cellular module antenna ports.
  • Low VSWR design maximizes power efficiency from transmitter to antenna.
  • 50-watt power handling capability supports high-power RF transmission needs.
  • Compact and flexible cable allows for neat routing in enclosures and field installations.

Applications

  • Extending antenna reach for 4G LTE, GSM/GPRS, and 3G cellular modules (SIM800, SIM7600, EC25).
  • RFID reader antenna connections and signal distribution.
  • IoT gateway and remote telemetry station antenna cabling.
  • Asset tracking and fleet management device installations.
  • Test bench and prototyping setups for cellular communication devices.

Frequently Asked Questions

What devices is this GSM antenna cable compatible with?

This cable is compatible with any cellular module or device featuring a standard female SMA antenna port, such as the SIM800, SIM7600, SIM7000, or EC25 series. It is designed for GSM 900MHz and DCS/3G 1800-2100MHz bands, making it suitable for 2G, 3G, and some 4G LTE applications where external antenna connectivity is required to improve signal reception in remote or shielded locations.

How do I connect this cable to my cellular module?

Ensure your cellular development board or module has a female SMA antenna connector. Screw the male SMA plug from the cable clockwise onto the module's port until hand-tight. Avoid over-tightening. Route the 3-meter cable to your external antenna, connecting the other male SMA plug to its female port. Verify the antenna is rated for the same frequency bands to ensure optimal VSWR and signal transfer efficiency for your specific IoT application.

What is the significance of the VSWR < 2.0 specification?

A Voltage Standing Wave Ratio (VSWR) below 2.0 indicates good impedance matching between the cable, connectors, and the connected antenna. This low value minimizes signal power reflection back to the transmitter, ensuring maximum power is delivered to the antenna for radiation. This efficiency is critical for maintaining strong link budgets and reliable communication range in IoT deployments using GSM or 3G networks, especially in low-signal environments.
