CC115LEM-868-915-RD, CC115LEM 868/915 MHz Reference Design for the CC115L RF Transceiver

CC115LEM-868-915-RD, CC115LEM 868-915 MHz Reference Design for the CC115L RF Transceiver. The reference design demonstrates good techniques for CC115L 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
