    Mirco Pizzichini
    Hi I've a problem with CC1120 RSSI register. I can see from User Guide that I can read two register (RSSI1 and RSSI0) for a 12 bits number, or using 8 bits from RSSI1, but result is different. Maybe I've to change other registers/settings to change RSSI resolution? Code I use is: cc112xSpiReadReg...

    Seishin
    Hi All, I achieve a receiver sensitivity of -125dBm with the current model using CC1020 and LNA.（400MHz band in Japan) Are more than -125dBm possible only by CC1120 reference design? When it is impossible, is the improvement possible by external LNA addition? Best Regards, Seishin
