Abstract :
The high level of feedback in transistor r.f. amplifiers is well known, and neutralizing must normally be regarded as merely reducing (not eliminating) this feedback. Criteria are established for gain and stability, and also for distortion of the frequency-response curve. Fromthe latter criterion, very simple practical design rules are arrived at: these are applicable to both single and multistage amplifiers, at any frequency. The results are summarized in a graph, which gives ´maximum seful gain´ and design data on the preferred (fixed neutralized) designsystem: corresponding data for a non-neutralized system are also shown.
