SEL_PATH_RFE_(1, 2): Selects the active path of the RXFE
0 – No path active
1 – LNAH path active (default)
2 – LNAL path active
3 – LNAW path active
EN_DCOFF_RXFE_RFE_(1, 2): Enables the DCOFFSET block for the RXFE
0 – disabled (default)
1 – enabled
Reserved
EN_INSHSW_LB1_RFE_(1, 2): Enables the input shorting switch at the input of the
loopback 1 (in parallel with LNAL mixer). Switch ON resistance < 3ohm
0 – switch OFF
1 – switch ON (default)
Should be '1' when RXFE loopback1 is NOT active
EN_INSHSW_LB2_RFE_(1, 2): Enables the input shorting switch at the input of the
loopback 2 (in parallel with LNAW mixer)
Switch ON resistance < 3ohm
0 – switch OFF
1 – switch ON (default)
Should be '1' when RXFE Loopback2 is NOT active
EN_INSHSW_L_RFE_(1, 2): Enables the input shorting switch at the input of the
LNAL
Switch ON resistance < 3ohm
0 – switch OFF
1 – switch ON (default)
Should be '1' when LNAL is NOT active
EN_INSHSW_W_RFE_(1, 2): Enables the input shorting switch at the input of the
LNAW. Switch ON resistance < 3ohm
0 – switch OFF
1 – switch ON (default)
Should be '1' when LNAW is NOT active
EN_NEXTRX_RFE_(1, 2): Enables the daisy chain LO buffer going from RXFE1 to
RXFE2.
0 – SISO (default)

DCOFFI_RFE_(1, 2)[6:0]: Controls DC offset at the output of the TIA by injecting
current to the input of the TIA (for I side). Default: 64
DCOFFSETx_RFE[6] – sign.
DCOFFSETx_RFE[5:0] – magnitude. When DCOFFSETx_RFE[5:0] 0,
0 current is inejction – no added noise.
DCOFFQ_RFE_(1, 2)[6:0]: Controls DC offset at the output of the TIA by injecting
current to the input of the TIA (for Q side). Default: 64
DCOFFSETx_RFE[6] – sign.
DCOFFSETx_RFE[5:0] – magnitude. When DCOFFSETx_RFE[5:0] 0,
0 current is inejction – no added noise.

ICT_LOOPB_RFE_(1, 2)[4:0]: Controls the reference current of the RXFE loopback
amplifier. Default: 12
I supply = I supply nominal *(ICT/12).
ICT_TIAMAIN_RFE_(1, 2)[4:0]: Controls the reference current of the RXFE TIA first
stage. Default: 12
I supply = I supply nominal *(ICT/12).
ICT_TIAOUT_RFE_(1, 2)[4:0]: Controls the reference current of the RXFE TIA 2nd
stage. Default: 12
I supply = I supply nominal *(ICT/12).
