Hello, just want to confirm the frequency range of the Micro. The product page states 30 MHz - 3.8 GHz, but the docs show a discontinuous range for TX and both RX paths. Specifically the TX path lower end is 30 MHz, but both RX paths lower end is 300 MHz. Is this correct or a typo?

If this is true, does anyone know if there are performance metrics or anecdotal comments for running the RX out of spec, for example RX at 30 MHz?

Thanks!

No, it’s just a persistent lack of clarity in the docs; the frequency bands which could be interpreted as gaps, rather instead simply _indicate where the RF matching networks are optimised_. There are no gaps in frequency coverage.

@Zack @Karolis can we make sure that schematics and documentation are clear on this.

ok thank you for the clarification, that makes sense.
