Sorry, it is connected, I was a bit slack with the schematic. You're right, when I adjust the pots so the input resistor is too low they do begin to oscillate. Am I better off having a small gain for the first stage then increasing the gain in subsequent stages? Or will the noise introduction be...
Hi all, I am working on designing an IF amplifier using opamps and just need some guidance as to whether I am on the right track as this is not one of my areas of expertise.
The input signal is from a frequency mixer, fed by frequencies of approximately 2.45GHz. I am only interested in...
That is great news, thanks for your help.
Can I assume the same will apply with a circulator, i.e: if my received signal (approx -85 dBm) is at a slightly different frequency to the transmitted signal, will the receiver still receive the different freqeuncy even though approximately 10dBm will...
Hi there. I want to use a frequency mixer with a LO power of 6 dBm and an expected RF input of -60 dBm. If the specified LO-RF isolation is 35 dB, what would be the effect of this insufficient isolation?
Would there still be an IF output of |Frf-Flo| at a lower power or would this not be seen...
