Part Number: AWR1642BOOST

In the recommended operating conditions,

VIN_13RF1(1-V internal LDO bypass mode)

VIN_13RF2(1-V internal LDO bypass mode)

The datasheet suggests 1V for LDO bypass mode. What does this mean? The AWR1642BOOST EVM use 1V3 to power up the chip.

Hello RJimmy,
The AWR device takes in 1.3V and internally generates a 1.0V using internal LDOs. If the user wants to save power we also allow directly feeding 1.0V on the same VIN_13RF1/13RF2 supplies by "bypassing" the internal LDO. This bypass is done via an API call in the mmwave link library.

Regards,
Vivek
