RPI-RFB

Meet the RPI-RFB, a powerful RF to Bits and Bits to RF converter in a compact RPI HAT form. The versatile device features a high-speed 10-bit DAC and patent-pending ADC architecture, with sampling rates up to 200MHz for ADC and 400MHz for DAC. The unit covers 400MHz to 3GHz and includes a two-channel RFFE interface for RF front-end control. Use it as a SDR or logic analyzer via Type C 3.0, or integrate it with your RPI’s GPIO header.

The RPI-RFB Usage

  • As a Software Defined Radio and if you add RF Front End with LNA, PA and Filters you can build a full-fledged Radio Subsystem.
  • On Hosts with Type C 3.0 interface, either as a SDR or as a Logic Analyzer at a time.
  • On RPI as a SDR, while the Type C 3.0 interface can be used as a Logic Analyzer.
  • As a two channel sdr receiver or a two channel sdr transmitter or one channel sdr full duplex transceiver at a time.
  • The patent pending ADC architecture on board allows for trade-off between sampling rate and resolution.

Software

The RPI-RFB is easily used by users of all major operating systems—Linux, Windows, and Mac OS. All you need is a Web Browser with support for WebUSB(Chrome, Edge etc.). The Web Application is hosted online and free to use for users of RPI-RFB. The Driver and Middleware Software supporting all the major operating systems running on Raspberry Pi, Will be Released with OpenSource license on GitHub by the time of RPI-RFB shipments.
