RF Power Output of MMZ25333BT1

Question asked by Sumit Karki on Oct 11, 2019

I want to use MMZ25333BT1 to output 2W of RF output at 2200 MHz. According to the datasheet, it seems to be possible (https://www.nxp.com/docs/en/data-sheet/MMZ25333B.pdf )

 

I designed a board based on MMZ25333BT1 (Figure 19 in the datasheet). I tweaked the bias resistors for Icq = 450 mA, so using R1 = 1.2k Ohm and R2 = 330 Ohm.

 

When I observed the RF power output, I could not get beyond 29.5 dBm. Is there some reason why I am missing out on the remaining output power? 

 

Thanks
