Hello everyone!
I have to make a system to detect magnitude of frequency from an RF one-port sensor/resonator (resonating at 4.5 GHz).
I wanted to first analyze the system on ADS tool. I have to make a VCO in ADS which should generate a 4.5 GHz frequency, may be it should tune from 4.3 GHz to 5.4 GHz. And, it should also have an offset feature.
I am very new to ADS tool. I have started learning it since yesterday.
Though, they have VCO in ADS, I tried to put it in my circuit but it is not working. I do not know what is the reason.
The snapshot of the ADS circuit is attached here. The signal from VCO is not going to Power Splitter.
Please see the images. I am trying a lot to search find the problem.
Would be great if anyone can help solve this issue.
Thanks!
Pictures:
1.Schematic Diagram of the Proposed Frequency Detection System
2. Entire system in ADS simulator till LPF. (after LPF the DSP kit will come into play, later on)
3. S-parameter output at mixer terminals (showing that VCO is not working)
4. VCO part (connected to power splitter)
