Which of the following reduces the likelihood of receiver desensitization?
Pick an answer to check it.
Answer: A. Insert attenuation before the first RF stage
Adding attenuation before the first RF stage lowers the strong signal so it does not overload the receiver. Raising front-end gain would make desensitization worse.
Tip: Attenuate before the first stage.
