CC1111USB_REFDES, CC1111 USB Dongle Reference Design for CC1111 System-on-Chip

CC1111USB_REFDES, CC1111 USB dongle reference design demonstrates how to make a compact USB dongle with the CC1111 System-on-Chip, a chip antenna in conjunction with a special PCB trace and single sided components mounting. The reference design demonstrates good techniques for CC1111 decoupling and RF layout. for optimum RF performance, these parts should be copied accurately. This is a 4-layer reference design with a discrete balun and a compact antenna solution. The antenna solution is recommended for applications operating in the 868/915 MHz frequency range requiring a small antenna solution
