CC1120DCDCEM868-RD, CC1120 with TPS62730 EM 868 MHz Reference Design. This RF Layout Reference Design demonstrates good decoupling and layout techniques for a low power RF device and a DC-DC converter operating in the 868 MHz and 915 MHz frequency bands. The battery current is reduced by more than 30% in TX at +10 dBm output power and by more than 35% in RX when using the TPS62730 + CC1120 compared to using CC1120 without a DC-DC converter
