I repair Satellite receivers and I often need to block the DC voltage on the IF line to do the repair . I need to block 13-18 Volts between 900mhz and 2Ghz while obviously letting the AC signal pass. If anyone can suggest a simple circuit I would greatly appreciate it.
I have a bit curious, why do you need to block DC on IF line ?
IF line in satellite receiver is on feeder, right? which repair method do you apply without DC voltage ?
