Re: AD630 circuit simulation, no line shown
Hello Tob, Please watch the SPICE-directives in my uploaded file CircuitAD630_1.zip. It contains a few SPICE-directives to achieve convergence. I also removed the absolute paths of the model files in

The purpose of this whole circuit is to test the AD630, so switching it with another op amp would solute my problem :/ Thanks though!

That ¡°high frequency¡± definition is what is used by the regulators (FCC and their cohorts) to describe transmitted and received signal frequencies. The term is much less precise in actual

Your first mistake is to post a graphic of your schematic instead of uploading it to Files =>Temp. When you have done that, people will try to run your schematic and find out what is wrong. You need

Hello Shikha, NXP has a lot of RF-transistors and they provide SPICE models as far as I remember. Others like Onsemi and Infineon have RF-transistors too. Best regards, Helmut
