I want to know if someone have any document or software to design muti-section firectional coupler? I use tunneling diode to detect RF power.
Second, I had designed log amplifer to transform RF power to DC voltage. What's differents between Directional detector and log amplier? I mean they both can transform RF to DC.
Thanks.
ps. I'm going to apply PH.D. in USA. My background is that.
A. Narror band superconductor filter (<1%) and Rx system
B. Ultra low noise LNA(1.9GHz NF<0.5 )
C.Ka band MMIC --> LNA and PA(1W)
D.Log amplifier
E.Ka band Rx
F. linear attenuator 0.1V for 1dB for high speed response time(<100ns)
G. X band VCO
Can you give me some advices on which group you know is suitable for me?
