Keywords:CC2520 CC2591  front end  RF transceiver 

The CC2520 is TI's second generation Zigbee/IEEE 802.15.4 RF transceiver for the 2.4GHz unlicensed ISM band. CC2591 is a range extender for 2.4GHz RF transceivers, transmitters and SoC products from Texas Instruments. CC2591 increases the link budget by providing a power amplifier (PA) for improved output power and a low noise amplifier (LNA) for improved receiver sensitivity. CC2591 further contains RF switches, RF matching and a balun for a seamless interface with the CC2520. This allows for simple design of high performance wireless applications.

This application note describes how to combine the CC2520 and the CC2591 in the same design. It further describes the expected performance from this combination as well as important factors to consider with respect to the layout and regulatory requirements. The combined CC2520 and CC2591 solution is suitable for systems targeting compliance with FCC CFR47 Part 15.
