Technology Stripline
Substrate εr = 3.4
Bandwidth 100MHz ... 512MHz
Power 200W
Coupling paths 2, symmetric to signalpath
Coupling <= -30dB
Directivity > 30dB
Frequenzy response
Correction of the frequenzy response of the directional coupler with analog cicuits (and digital)
<= 2dB (0.2dB)
Rectification and AM - Demodulation of coupled signal  

 

The thesis was written with LATEX.

 

 

Thesis (Physics)

 

Spring/Summer 2014, at the University Observatory Munich.
