RFI_HF and RFO_HF pins in SX1276

Semtech Transceivers SX127x family
#1

Hi,
I am designing a single band transceiver using “RF_LF” pins of “SX1276” chip, thus no need to use “RF_HF” pins (#21 and #22) in the design. Should the unused “RF_HF” pins be kept floating or pulled up/down? The datasheet does not provide any info about the internal pull resistors!

Thanks in advance,
BR

If the RF_HF pins on the Sx1276 are not used they can be left open
