RF Wireless Link for 915 MHz ISM Band

• We provided a quick turnaround prototype design for a customer. The project involved designing a wireless link for sending and receiving digital data. The transmitter used FSK modulation at 915 MHz to send the digital information. The transmit power levels were restricted to less than 1 mW. The receiver provided front end filtering, low noise amplification, and demodulation of the FSK signals to digital information. Most of the components used were RF integrated circuits from RF Micro-Devices. The link was field tested also.
