Hi,

When designing a receiver, do you prefer to put the limiter before the bandpass filter or the bandpass filter before the limiter?

Assuming the filter components have high-power handling. What are the concerns?

Thanks
 

This isn't primarly a power-handling question. Consider that there are usually out-of-band signals present at the receiver input. Analyze the different behaviour for both cases, this answers your question.
 

When is about limiter in a receiver, most probably is about receiving a constant modulation signal (as FM or others).
In this situation, from a system point of view, the limiter is the last stage before demodulator/discriminator, and the BPF is placed before it.
