A comparison of voltage-tuned magnetrons with M and O types of backward-wave oscillators

One of the inherent characteristics of the voltage tuned magnetron is its capability of being electronically tuned over a wide range in frequency. It is informative to compare the vtm with M and 0 backward-wave oscillators, which are also capable of wide electronic frequency tuning. The voltage-frequency characteristics, power frequency characteristics, size, weight, and complexity, will be among the items compared.
