Keywords:CC2530 Zigbee  CC2591 front-end  implementing CC2530 CC2591 

The CC2530 is TI's second-generation Zigbee/IEEE 802.15.4 RF SoC for the 2.4GHz unlicensed ISM band. This chip enables industrial grade applications by offering selectivity/co-existence, link budget and low voltage operation. The CC2531 is identical to the CC2530 with the addition of an USB interface. CC2591 is a range extender for 2.4GHz RF transceivers, transmitters and SoC products from TI. CC2591 increases the link budget by providing a power amp for higher output power and LNA for improved receiver sensitivity. CC2591 contains RF switches, RF matching and a balun for a seamless interface with the CC2530. This allows for simple design of high performance wireless applications.

This application note describes how to implement the CC2530 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 CC2530 and CC2591 solution is suitable for systems targeting compliance with FCC CFR47 Part 15.

The RF front end of CC2530 is the same as the ones being used in CC2531. The presented results in this application note are therefore also valid for CC2531.View the PDF document for more information.
