How to enhance output Voltages of RF-PA

TL;DR Summary

How I can boost the output voltage to the desired level i.e. 15~18Vpp.

Hello everyone, I’ve been working on modifying the RF Power Amplifier circuit, and I’ve made good progress (schematic is attached below). However, I’m now facing a small issue – I’m currently getting an output voltage of around 9Vpp, but I need it to be in the range of 15–18Vpp. I’ve tried changing the values of resistors R6, R7, and R8, but I haven’t been able to reach the desired voltage level. I would really appreciate any advice on how I can boost the output voltage to the desired level. Thanks in advance for your help.

1. Increase Vdd.
2. Raise the output impedance of the band-pass filters.
