dear 7rots51
limiter is my chalenge too.and i gona make it.i think one important point that you have to pay attention is frequency.and the other is your device where limiting take place through that.for example i have seen some waveguide port.maybe you gona make some coaxial one??
ask this question and then we can go ahead step by step
Assuming you have a way of detecting the modulation, a low power oscillator will lock to an incoming signal over a limited bandwidth and thus provide a constant output level. This is useful for FM but not AM.
