Application Note AG312. Design with pin diodes Rev. V3. Introduction The PIN diode finds wide usage in RF, UHF and microwave circuits. It is fundamentally a device whose impedance, at these frequencies, is controlled by its DC excitation. A unique feature of the PIN. diode is its ability to control large amounts of RF. power with much lower levels of DC. PIN diode Modeling The PIN diode is a current controlled resistor at radio and microwave frequencies. It is a silicon semicon- ductor diode in which a high resistivity intrinsic I-region is sandwiched between a P-type and N-type region. When the PIN diode is forward biased, holes and electrons are injected into the I-region. These charges do not immediately annihilate each other; Figure 1. Instead they stay alive for an average time called the carrier lifetime.
