Hi All:
I purchased one of these items..note attached PDF wit all details. Proceeded to break the PCB due to a yanked cable and was in the process of recalculating the 'impedance' of the microstrip for 1.6mm FR4.
I realized that it adds up to several hundred ohms.
My question is this...why would a 50 ohm RF signal require a several hundred ohm microstrip (to couple some signal to a detector) and then connect to another 50 ohm output? See Note 4 on page 11.
PS: i asked the author...he does not know.
