I have to design a CLASS B push pull power amplifer. for the operating frequncy = 402 MHz, it should able to transfer 500uwatt power to 50 antenna. i am using Vdd =1.8V
using calculation i got RL=810 ohm.
i.e RL = Vdd ^2 /8*Pout = 810 Ohm. so i need a matching networt that can see 810 ohm from 50 ohm antenna. i am using Tapped Capacitor resonator, the values i got L = 2.393nH , C1 87.139pF , C2 = 263.59pF.
The design is atteched in figure. the think i need to know is
how to choose the value of coupling Capacitor Cdc as show in fig .
and also Cc and Rbias
