Global Data Usage Accelerating Unprecedently

Increased data usage on smartphones is driving demand for more spectrum and more frequency bands. More bands mean more fixed frequency filters in mobile radio front ends. This is causing size, space and weight issues.

Fixed frequency filters are fundamental to the operation of all FDD wireless devices in use today. They ensure that their built-in transmitters and receivers can simultaneously send and receive signals whilst preventing self-interference from compromising their efficiency. As new frequency bands are introduced, the component count per device increases in line. This is untenable long-term.

Breakthrough Technology That Overcomes RF Interference Challenges

Forefront RF is poised to redefine mobile radio front end designs. Based on our patented Foretune technology, we’ve developed a full RFFE module that incorporates a power amplifier, low noise amplifier, coupler and a tunable duplexer that dynamically self-configures according to available frequencies and/or services needed. The result:

 

  • Less PCB space
  • More bands
  • Less cost

How it Works

Foretune™ technology resolves RF interference and challenges by leveraging self-interference cancellation techniques. Similar to noise cancelling technology in headphones, Foretune™ dynamically cancels all unwanted RF signals (emitted by inbuilt transmitters and receivers in mobile radio front ends) by adding inverted versions of those signals. Aimed at 3G,4G and 5G equipment, Foretune™ technology is set to replace the different components found in traditional radio front-end modules with a smaller integrated solution capable of supporting more bands. The higher the band count, the greater the space saving.
