摘要：

When 2.4G RF technology is applied to mobile payment, power consumption and the distance of swing card become crucial challenges. This paper presents an architecture and circuit design for low power 2K/4K rate RCC(range-controlled communication) chip for waking up and configuring the 2.4G RF chip. The signal is transmitted by the low frequency electromagnetic field, which attenuation rapidly with the distance increase. Three-stage programmable gain amplifiers are used to amplify signals. Digital-to-analog converters and comparators are design for judgment the transaction approach and departure.
