CC110LEM-868-915-RD, CC110LEM 868/915 MHz Reference Design for the CC1101 RF Transceiver

Description

• CC110LEM-868-915-RD, Reference Design demonstrates good techniques for CC110L decoupling and RF layout. for optimum RF performance, these parts should be copied accurately. This is a 2-layer reference design with a discrete balun and two antenna options. A small and compact PCB helix antenna that will be useful for applications requiring a high antenna efficiency in a compact area. The 868 MHz PCB helix antenna is only 19 x 12 mm (L x W) and has an efficiency 70 %. By changing 2 discrete component values, this antenna can also be matched to 915MHz. PCB footprint for a single ended 50 ohm antenna. The RF section is designed for operation in the 868 MHz and 915 MHz frequency bands
