Regarding LT5537 s1p file to simulate the input matching network and RF input vs output voltage

What about such idea:

• design matching network and simulate (or calculate) the RF voltage at input of detector
• The LT5537 has a high impedance input, RF voltage is converted to DC voltage with slope 20mV/dB

Yes,

But to do the simulation, could you please provide the simulation file?

I used Table 1 in the datasheet and I converted model to s1p file. The content of the file is below, I was not able to upload it.

Hello, 

But I need to simulate LT5537 input matching network having TCM2-33WX+ Balun and plot a graph of Vout vs input power at different frequency sweep of 35-60 MHz.

Is there any way to do this, because using S1P , it is only possible to check S11. but I want to figure out its effect on deviation on Vout vs input power?

Request you to provide guidance for the same.

Hi.

I have simulated for you your circuit. 50 Ohm input is connected via XFRM TCM2-33WX+ and matching via simple 100Ohm resistive load. As you can see, matching is pretty good. 

I.L. of XFRM is ~1dB and voltage gain is 3dB due to impedance transformation. Thus it adds 2dB or 20mV/dB*2dB = 40mV_DC. 

Hello,

Thank you for your detailed support and guidance.
