ABSTRACT
The article focuses on the positive-intrinsic-negative (PIN) diode antenna switch. The features of the PIN diode is compared to the electromechanical relay used for the antenna changeover switch. The PIN diode allows the diode to be used at higher frequencies by reducing the capacitance at the junction. PIN diodes are able to handle large power levels with minimum distortion, good isolation and low insertion loss. The process on how the PIN diode is used to switch antenna is also discussed.
