  8. 3. What is FPRF Technology? The FPRF Company – Ultra flexible RF solutions Confidential

  9. What is FPRF?  The FPRF is a radio frequency transceiver IC that mimics the concept of an FPGA in the RF domain to deliver a multi-standard, multi frequency device  The FPRF transmitter takes a digital data stream and converts it into wireless signals, while the receiver perform the inverse operation  The FPRF transceiver offers the capability to program key parameters like the RF frequency, gain, and bandwidth  All major elements within FPRF have programmable Bias circuits and could be powered down and/or bypassed  All major elements within FPRF could be isolated and used as individual circuits  Main features: The FPRF is programmed by customers, not in the factory  The tools allow customers to experiment and change parameters on the fly  Confidential 9 The FPRF Company – Ultra flexible RF solutions
