I do like that their spec is clearly just a copy and past of the underlying UWB chip specification.
They include the lines:
- Worldwide UWB Radio
- Regulatory compliance
I’d love to see their definition of regulatory compliance. It probably involves never transmitting.
Looks like they also sell a version with a small processor added that can perform TWR and basic localisation. The claim ranges up to 1 km.
Meanwhile in for those of us who need to comply with the regulations generally the parts are easily capable to hit the FCC limit without needing an external amplifier. So unless you are using a very poor antenna an amplifier on the transmit side is pointless if you need to stay under the -41.3 average/0 dBm peak limits.
Where an amplifier can help while staying within limits is on the receive side. You can boost the sensitivity of the receiver that way. But of course amplifying somethings that’s getting lost in the noise is both harder (you need a very low noise amplifier) and also less beneficial to simply blasting the signal louder to start with.
