Hello Team NXP,

We are using A2T07D160W04SR3 RF Power LDMOS Transistor in our application.

We are biasing the PA as per the datasheet ie.VDD = 28 Vdc,IDQA = 450 mA, VGSB = 1.2 Vdc.

where Carrier amplifier is biased for fixed current of 450mA and peak amplifier to fixed voltage of 1.2V,


am i right in biasing the PA or we should be adjusting the carrier and peak amplifier bias to get optimum results?


Please help me out in this.
