Hi,

 

I need to design a 433MHz remote control:

 

° 433Mhz, max : 10 dBm
° Distance Range : 500 m 
° Antenna is a PCB trace


Regarding ADF7023, which modulation (ASK, FSK, OOK...) do you advice for :


    Better transmission quality against spurious
    Better BER
    Better spectral efficiency
    Better power efficiency ?
    Longer distance range
