Hi guys

I am looking at this datasheet here (Microchip RN2903, LoRa Module):
http://ww1.microchip.com/downloads/en/DeviceDoc/50002390C.pdf

• On the first page, it says it has receiver sensitivity down to -146dBm. What is this receiver sensitivity? Is it save as Link Budget?
• And what is this IIP3 stuff? I googled it, but still don't understand.

Cheers

 

Receiver sensitivity is the minimum signal the receiver can recover. IIP3 is the third order intercept point referenced to the input (input intercept point, 3rd order). IIP3 is an indication of the linearity of the part.
