AWR1243: AWR1243P power supply for 3Tx simultaneous mode

Expert 7150 points
Part Number: AWR1243

Hi Experts,

 

My customer is planning to use 3Tx simultaneous mode. In this case, the power supply will be

A) VIN_13RF1,2 : Supply 1V

B) VOUT_PA   : Supply 1V

 

Per datasheet Table 5-3 (page 19), there is following description: 

(1) 3 Transmitters can simultaneously be deployed only in AWR1243P device with 1V / LDO bypass and PA LDO disable mode. In this mode 1V supply needs to be fed on the VOUT PA pin. In this case the peak 1V supply current goes up to 2500 mA.

 

Does it mean A+B goes up to 2500 mA? Or does only B go up to 2500mA?

 

Best regards,

Ken
