Theoretical and Experimental Study of the InP/InGaAs PIN Diode for Millimeter-wave MMIC Applications

The DC and AC characteristics of InP/InGaAs PIN diodes have been investigated based on theoretical and experimental approaches. The switch performance of the PIN diode has been studied using a 2-D CAD simulator (Silvaco). Experimental data from a fabricated InP/InGaAs PIN diode was compared to the theoretical results. The developed InP/InGaAs PIN diode has demonstrated a 0.39 V turn on voltage, a 34 V breakdown voltage and a 5.23 THz cutoff frequency.
