This complete ‘antenna to audio’ module can be produced in standard mass-production facilities, supporting local manufacturing in emerging markets. 

CML Micro today announced the global release of the DRM1000 module, a comprehensive Digital Radio Mondiale (DRM) broadcast receiver designed to empower consumer radio manufacturers with low-cost, low-power DRM radio solutions. Developed in partnership with Cambridge Consultants, part of Capgemini Invent, the DRM1000 combines CML Micro’s expertise in wireless IC design with Cambridge Consultants’ proficiency in low-power digital signal processing. This collaboration has produced the smallest, most cost-effective, and lowest power DRM receiver on the market, consuming 80% less power than existing DRM receivers.

The key specifications include:

  • Supports existing LF/MF/HF and VHF frequencies alongside analogue services
  • Includes Emergency Warning Functionality (EWF) for disaster and early warning services
  • Contains all necessary hardware, software, IP, and patent licenses for dual-mode DRM-capable receivers
  • No additional fees for software licenses or royalties
  • Pre-certified to the EU Radio Equipment Directive
  • Compact size: 42mm x 25.4mm x 5mm
  • Ideal for portable and renewable-powered devices

It enables manufacturers to quickly add DRM to current and future analogue AM/FM/DRM radio designs. DRM’s capability to deliver high-quality audio and digital content across Low, Medium, High, and VHF frequencies makes it ideal for both urban and rural areas, requiring minimal transmitter infrastructure.Radio manufacturers can utilize it with the DE9180 kit to test and develop new DRM1000-based designs. 

Global Availability and Future Enhancements 

It is now available through distributors such as Mouser, DigiKey, RFMW, and others. Additionally, an evaluation and prototyping kit, the DE9180, is available for $199.  The company plans to enhance the DRM1000 with short-range wireless connectivity and additional features throughout 2024.

Matthew Phillips, Product Director at CML Micro, states, “The DRM1000 is a world-class product that will make DRM-capable radios accessible to all. It will help portable radio suppliers design cost-effective DRM radios optimized for extended battery life, democratizing DRM radio for countries implementing new digital broadcast networks.”

Tim Whittaker, Project Leader at Cambridge Consultants, adds, “This breakthrough in DRM receiver technology can bring affordable, reliable radio to billions globally. It addresses a key barrier to widespread DRM adoption, offering a cost-effective, low-power solution for manufacturers to connect listeners in low-income, previously unconnected communities.”
