图1CC110L内部结构图

The CC110L is a cost optimized sub-1 GHz RF transceiver 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. Two CC110L transceivers together enable a low-cost bidirectional RF link.
