A: Typically, they are constructed with PIN diodes. A PIN diode is simply a p-n junction diode that is designed to. have a very small junction capacitance (0.01 to 0.1 pf). A Sort of the opposite of the varactor diode! To see why this is important, recall diode small signal analysis. from your first electronics course.
