Using PIN diodes is new to me. I've read a lot of the app notes from various vendors like MA/COM, AVAGO, MICROSEMI. My problem is I don't understand how to bias the pin diodes. All of the app notes shows the rf path with the pin diode "isolated" with dc blocking caps. Voltage goes through an inductor, the pin diode, and then another inductor. No problems yet. But:
What limits the current?
Also, someone sent me a T/R switch sketch. It has some "U-LINE" depictions.
What is a U-LINE?
Thx.
