1. The problem statement, all variables and given/known data I need help with finding an operational amplifier that could be cascaded with itself to produce a total gain of around 100,000, or 100dB. It also needs to be operational up to 1.5 MHz. This is for an rf amplifier for an AM radio I am building. 2. Relevant equations 3. The attempt at a solution Most amplifiers seem to amplify correctly during the first stage, but the second stage either doesn't amplify at all or it seems to drop almost back to the input values. This could be due to bandwidth issues I suppose. The most gain I've been able to achieve is 1,000. Thank you for your time.
