The A7105 is a low cost single chip 2.4GHz transceiver. With on chip fraction-N synthesizer, it can support the application of data rate up to 500KHz and frequency hopping system. A7105 also supports the packet handling, data FIFO, error forward correction and SPI interface. That makes A7105 easy to be used together with a low cost and low speed micro-controller. The device is in QFN4X4 20 pin package.
