That should work. Do note that the maximum output power for the SE2425U exceeds the BLE limit of 10mW so you will have to adjust the power you send into the amplifier.

Hi,

Thanks for the reply.

We are planning to fuel gauge solution to measure the battery.use Can we use skyworks SE2425U as range extender to increase the effective range?if not do you have any suggestions?

Hi,

Yes, you can definitely use a range extender such as a PA or LNA. If you want to use your phone as enabler you are likely to be limited by the range of the BLE chip on your phone.

You can use the internal ADC set to listen to VCC to be able to read remaining battery voltage. See the adc_simple example for implementation.

Best regards,
