Using PIN Limiter Diodes In Receiver Protectors

A limiter PIN diode with a three-layer design can protect a receiver from large input signals while allowing the receiver to function normally when large signals aren't present. A diode can also be used as an input-power-controlled RF variable resistance to produce attenuation that is a function of the diode characteristics, as well as the incident signal amplitude. This application note describes the use of PIN limiter diodes in receiver protectors in detail, as well as their many design characteristics and benefits. Download the full paper for more information.
