Cc2530 + rfx2401c ZigBee Module

Recently, a company's project needs to use ZigBee, and has purchased an online ready-made module. The communication distance is very long, but the protocols are not public, and the price is very high, which is inconvenient to use, finally, I decided to use my own canvas. At first, I used the combination of and, and found that the effect was very poor. The main reason was that there were too many peripheral components and the parameter was not properly tuned. Finally, I found someone using rfx2401c on the Internet, after that, I found that the chip had two decoupling capacitors for external devices, which was very convenient to use, but there was no information. I sent an email to foreigners, but I did not expect to reply quickly, I sent the datasheet of rfx2401c to me, And then successfully designed this module with power amplifier. Although there are so many ZigBee modules, there are very few related circuits or design materials, I would like to share with you here.

There are very few components and no external buttons or LEDs are needed to remove them. The wiring is very simple. I use 0603 resistor and capacitor, and the effect is better.

The schematic diagram is like this. PCB may take some time. We can't test it without related RF instruments, but at least meet the design requirements of the company.
