I'm designing remote controller based on NRF24L01 and STM32. I want to use SMA antenna. My question is regarding power amplifier (PA). When is it necessary to use one? The range I'm aiming for is 20+ meters. Every commercially available module with NRF24 and SMA antenna has PA, but I would like to save on cost and space on PCB. The NRF24 datasheet says that recommended load impedance is 50 Ω. Is it therefore possible to use SMA connector and antenna with 50 Ω impedance?

- **EDIT:**
- Is there a way to calculate the approximate range of this remote controller? I have seen some advanced software that can simulate antennas (too advanced for me), but I want to know what will be the approximate range. Or is it just easier to test this and then add PA later on if it is necessary.

Power amplifier for remote controller
I'm designing remote controller based on NRF24L01 and STM32. I want to use SMA antenna. My question is regarding power amplifier (PA). Is it necessary to use one? The range I'm aiming for is 20+ meters. Every commercially available module with NRF24 and SMA antenna has PA, but I would like to save on cost and space on PCB. The NRF24 datasheet says that recommended load impedance is 50 Ω. Is it therefore possible to use SMA connector and antenna with 50 Ω impedance?
