RF front end and antenna

Whether SX1262 share the same RF front end for all frequencies(433MHz,868MHz,915MHz) or there will be any change in hardware? If so, can a single ISM LoRa antenna can be used for all frequencies?

LoRa modules have components that matche the antenna impedance to the LoRa RF at the modules designed frequency. There are also filter components, based on the frequency band of the module, to eliminate harmonics.

Its possible to make antennas that are correctly resonant on several bands, but easy it is not.

Thank you stuart for your reply.

For SX1262 in 868MHz, in the application design provided in datasheet the values for inductor L2 is 0R and for capacitor value is not mentioned even in the BOM. Can I know the details regarding this.
