What can replace nrf905 chip?

[Jesen]

Hi,my friend,

I have been using nrf905, but its performance is very bad. Have a compatible chip nrf905 data communications? Working frequency 433 MHZ,100 KBPS baud rate.Please recommend a chip,Can you help me?

Hi,

If you want better performance in the 433MHz band the nRF905 chip is the only option we currently have.

However, depending on your application, the nRF51 series might fit your requirements. It also offers a much more compact and energy efficient solution.

Best regards,

Øyvind

Thank you for your answer.I use the nrf905,At one end Use the PCB antenna, on the outside part of the metal.Using the results, said communication distance is shorter than 40 meters, easy to loss of data.

In China,I've asked nrF905 agent,XUN TONG company，www.freqchina.com/.../.They didn't give me any feasible solution.

Can you send some nrF905 and PA, and receiving amplifier circuit of nrF905 information for me?I need technical support, thank you very much.
