图1CC113L内部结构图

The CC113L is a cost optimized sub-1 GHz RF receiver for the 300–348 MHz, 387–464 MHz, and 779–928 MHz frequency bands. The circuit is based on the popular CC1101 RF transceiver, and RF performance characteristics are identical. The CC115L transmitter together with the CC113L receiver enable a low-cost RF link.
