The diode limiter is versatile with moderate power handling.
The diode limiter is the only completely self-contained passive receiver protector technology.
The passive all-solid-state diode limiter is normally the desired solution for most receiver protector applications.
Although great advances have been made, most applications involve power and duty cycle characteristics that exceed today's diode limiter capability.
This stage would be followed by a passive diode limiter that would provide cleanup limiting during normal system operation as well as a measure of protection against external signals.
The pre-T/R tube serves as a prelimiting device whose function is to cut the power to a level that can be handled by the diode limiter.
The schematic diagram of a PIN diode limiter is shown in Figure 12a and the fabricated chip is shown in Figures 12b and 12c.
At the present time, it is possible to realize a 10 W PIN diode limiter or a 1 W Schottky barrier diode limiter, whereas in the hybrid form PIN diode limiters up to 400 W have been realized.
