Before revision: However, a magnetron is an oscillator and a CFA is an amplifier ; a CFA's RF circuit (or slow-wave structure) is similar to that in a coupled-cavity TWT.
After revision: (although a CFA can be driven to oscillate by application of improper low voltages as cacn any amplifier)However, a magnetron is an oscillator and a CFA is an amplifier ; a CFA's RF circuit (or slow-wave structure) is similar to that in a coupled-cavity TWT.
