Abstract
Described is a frequency selective limiter (FSL) module comprising a cascade of an FSL and a functional limiter (e.g. a conventional semiconductor limiter comprising a PIN diode) with steady state limiting and power threshold values selected such the FSL module provides suppression of a spike leakage power and while still enabling frequency selective limiting.

A frequency selective limiter (FSL) module comprising:
- a radio frequency (RF) ferrite-based FSL having an input, an output and a steady-state limited output power characteristic;
- and
- an RF functional limiter coupled to an output of the ferrite-based FSL, wherein the RF functional limiter is a semiconductor limiter.
A frequency selective limiter (FSL) module comprising:
- a radio frequency (RF) ferrite-based FSL having an input and an output;
- and
- an RF functional limiter coupled to an output of the ferrite-based FSL, wherein the functional limiter is a gas discharge device.
A frequency selective limiter (FSL) module comprising:
- a radio frequency (RF) ferrite-based FSL stage having a spike leakage characteristic;
- and
- an RF functional limiter stage coupled to an output of the ferrite-based FSL stage, wherein characteristics of the RF ferrite-based FSL stage and the RF functional limiter stage are selected such that the combination of the RF functional limiter stage and the RF ferrite-based FSL stage provide the FSL module having a spike leakage characteristic which is reduced compared with the spike leakage characteristic of the RF ferrite-based FSL stage.
A frequency selective limiter (FSL) module having an FSL module input and an FSL module output, the FSL module comprising:
- one or more FSL stages, each of the one or more FSL stages comprising a ferrite and having an FSL stage input, an FSL stage output and a steady-state limited output power characteristic;
- and
- one or more radio frequency (RF) functional limiter stages, each of the one or more RF functional limiters coupled to an output of at least one of FSL stages.
A frequency selective limiter (FSL) module comprising:
- a radio frequency (RF) ferrite-based FSL having an input, an output and a steady-state limited output power characteristic;
- and
- at least one RF functional limiter stage integrated with the RF ferrite-based FSL.
