Receiver protector is necessary requirement of Front End Radar Receivers from intentionally transmitted high power. Switch Limiter can offer one of such protections to Receiver circuits. The sizes of solid state switch limiters are very smaller with respect to traditional high power cavity duplexer/diplexers. These solid state switch limiters can also be integrated in planar PCB assemblies of Receivers. This paper gives design of switch limiter with power handling of 2KW (3.2% duty cycle.) in S Band with discrete components. This design has been implemented to achieve better than 40dB attenuation. Limiter is included in design to protect Low Noise Amplifiers, which is prone to damage if exposed to high level RF signals. Same design can offer protections for Secondary Surveillance Radars (IFF systems in multiple mode of operations) with little optimization of components.

When the bias is off (0 V), the depletion-mode TPD protects the receiver circuits because the FET presents a low impedance across the line.
