Important RF Integration Notice

This 2 W transceiver module is not CE certified. It is an integration component for experienced builders and is not a complete transmitter or ready-to-use repeater.

External, band-specific RF output filtering is not included and must be added by the system builder. A power amplifier can amplify harmonics and other unwanted emissions. Using this module—especially with a PA—without suitable filtering can cause harmful interference and may violate local radio regulations.

Before connecting the completed system to an antenna, use a 50 Ω test load and suitable RF test equipment to verify output power, harmonics, spurious emissions, stability, and thermal performance. The system builder is responsible for the final design, testing, licensing, and regulatory compliance.

2 W Analog Transceiver Module for Repeater Builds

The 2 W Analog Transceiver Module is a compact RF building block for custom analog repeater, simplex-repeater, EchoLink, SVXLink, and radio-linking projects. It combines a band-specific FM transceiver with a Wolfson WM8960 audio interface on a fully assembled PCB.

This product is intended for integration into a complete RF system by an experienced builder. It is supplied as a module—not as a finished repeater—and requires the correct supporting hardware, RF filtering, enclosure, power supply, antenna system, and system-level testing.

Choose the Correct Band Version

  • UHF version: 400–480 MHz
  • VHF version: 134–174 MHz
The UHF and VHF models are separate, band-specific product versions. Select the version that matches your repeater design and authorised operating frequencies.

What You Need to Complete a Repeater

The exact system depends on the repeater architecture, but a complete installation will normally also require:

  • A compatible controller or host with correctly configured repeater software
  • A clean, regulated power supply
  • A suitable shielded enclosure and adequate thermal management
  • A band-specific RF output filter rated for the intended power
  • A compatible power amplifier if more than the module’s nominal 2 W output is required
  • A duplexer, cavity filters, isolator, or other site-specific RF hardware where required by the repeater design
  • A correctly matched 50 Ω load, feed line, and antenna system
  • RF test equipment and system-level verification before on-air use
Module-only product: Power amplifier, external RF filters, duplexer, controller, enclosure, power supply, feed line, and antenna are not included unless they are explicitly listed as part of a separate bundle or selected option.

Mini-FAQ

  • Is the 2 W module CE certified? — No. It is supplied as a component for integration, and the completed system must be tested and assessed by the system builder.
  • Which bands are available? — Choose either the UHF version (400–480 MHz) or the VHF version (134–174 MHz). They are separate product versions.
  • Is this a complete repeater? — No. This is a transceiver module used to build a repeater or another RF system.
  • Are the required RF output filters included? — No. The builder must add suitable band-specific filtering and verify the complete RF chain before transmission.
  • Can I add a power amplifier? — Yes, as part of a properly engineered system. The PA must be compatible with the module’s output and must be followed by suitable filtering. The completed system must be tested for harmonics, spurious emissions, stability, and thermal performance.
  • Can I connect the module directly to an antenna? — Not before the complete RF chain has been correctly filtered, matched, tested, and confirmed to comply with local requirements.
