@f95toli: I used your mini-circuits suggestion and found the http://www.minicircuits.com/case_styles/TTT167.pdf" . This should be a replacement for the other chip; its cheaper and it looks like we can actually manufacture the board for this part. Thanks very much for the help.
@berkeman...
My group had a design based on the http://www.analog.com/en/rfif-components/log-ampsdetectors/ad8302/products/product.html" which was going to do our task of phase detection by use of what I can best tell was just some log amplifiers and .
Well the AD8302 is a TSSOP package and I cannot...
My scenario:
LNA 433MHz signal (21dB) from antenna and the difference between the two signals with a 4.1dB gain. I would like to take the result of the difference amplifier an produce a DC value that is proportional to the output.
Question 1:
What type of circuit would lower the frequency...
So to test my understanding of the system I should do it like this:
1) Capture the incoming signal.
2) Turn it to an intermediate frequency (IF).
3) Capture the power of that converted signal (in dB's and dBm's).
4) Quantize (or digitize) that output.
5) Deliver to FPGA.
Is my understanding...
I am trying to build a RSSI for a incoming signal I would like to have the system to be the highest accuracy available. But my problem is that I understand very little about what RSSI actually is.
We are in the prototyping phase of the system so the frequency isn't set in stone yet. What is...
