VHF Power Amplify Circuit

[nhutdtvt]

Hi all!
I have a circuit schematic ( in OrCad capture *.dsn) on VHF Power Amplify.
I post here for you. If you were interested in this circuit, you could discuss with me!
I built once for 98MHz and it work OK! So if you need some advices asking me!

Regard, nhutdtvt

Can you please post your schematics in gif, pdf or any general format. Only members which have Orcad can read your post now.

 

[nhutdtvt]

sorry!
I printed the schematic into *.DPF file.
Hope that you could read it.
Regards, Nhutdtvt

Some basic specifications on similar design you can find here:

if i wanna use the 145 MHz frequency
What do I need to set??
please help me

It's a basic class C amplifier, but the design details can't be seen from the schematic. So what you are exactly asking for?

You can also implement the reference circuit from the MRF317 datasheet, which is rather similar.

I want to design a power amplifier that works at a frequency of 145 MHz
Do you have a circuit that is suitable for my PA?
ok, I'll look at the MRF317 data sheet
