Re: Bias Tee-Design or Circuit

Does it mean it is impossible to implement inductor with microstrip reaching 40GHz? I was hoping to find some solutions using microstrip, but it seems I may need to change my direction, searching for discrete components...

Getting a reasonable inductor to 40 GHz with microstrip (especially on a soft substrate) will be very difficult. I'd suggest going for a broadband inductor, like some of the broadband Coilcraft offerings.

Pay a few dollars and save yourself hours and hours and hours and hours and hours and hours and hours of design, fabrication, measurement, redesign, fabrication, measurement, redesign, fabrication.............. to get it right.

You can use microstrip + lumped indcutors.
