Nonlinear and transient microwave and RF modeling of the PIN diode

Models for analyzing the PIN diode in switch, attenuator, and limiter applications are presented. A nonlinear forward-bias model is outlined. The resulting nonlinear transfer functions are evaluated out to third order and discussed in terms of distortion intercept points for series- and shunt-mounted PIN diodes. The model is compared with series circuit experimental data. A transient PIN diode model is introduced and used to study the effects of operating frequency and diode geometry on limiting characteristics.<
