Power Amp for 2.4Ghz frequency

Power Amp

Hi:
I have a problem with a design of a power amplifier in 2.4Ghz.He found that I have to use the S-parameters great signal, they are taken off the curves VI transistor, my problem is to choose a model for moving from curve VI-S parameters of great signal and can not get the models someone knows anything about this?

Thx

Hello wakuhuaco,


If I understood your query correctly then you looks have problems in PA design using Vendor device S-parameter file right?

In order to design Power Amplifier (PA), you need to have nonlinear model (Spice)
of the device so that you can get IV curves, DC Bias analysis & spectrum plots...

If you have only S-parameter file (*.s2p) then it is difficult to design PA design and
you can do linear analysis only with s parameters...

Go through this for details on PA analysis

Re: Power Amp

ah ok thx manjunatha_hv.
Then I have to ask the manufacturer of the device model nonlinear transistor
Thx

Hi Manju,

The tutorial by AWR is excellent. Well, do you know about any power amplifier modules in the market capable of operating in 400-450MHz with an output power of 20W. We came across a device from Sirenza, but we are struggling hard to linearise it for our application (TETRA).

Regards,
Vishnu.

Re: Power Amp

Hello Vishnu,

I found Centellax products may be good or fits your application...
These are very broadband amplifiers...
