€8-30 EUR

Paid on delivery
I am trying to build a collpits oscillator of the resonance frequency of 433Mhz. I have built the whole circuit however I can't find an OP-AMP that is available in the German market which can give me the perfect sinusoidal signal for the frequency given. I just need help in finding an Amplifier that can give me perfect Sin signals when I do simulation on LTspice for the resonance frequency of 433Mhz (It should be in stock in websites in Germany -> I can even provide the name of the websites)

Hello, I am an electronics and telecommuncation engineer and my major is wireless systems design. So far I have done many circuits related to RF design so I am quite familiar with the components. I can already give you the model name of the transistor and if you cannot model or if you do not have the such model in LTSpice I can model the transistor with it's characteristics. So just let me know and I will do my best to help you. Best regards
