What is RF Output Power in M-Type Microwave Tubes ?

In M-type microwave tubes, also known as cross-field tubes, RF output power (P_out) refers to the amount of microwave energy emitted by the tube after amplification.

What are its Applications ?

Radar Systems: M-type tubes are used in high-power radar transmitters for applications like long-range air traffic control, weather radars, and military defense systems. Their ability to generate high peak power pulses makes them suitable for long-distance target detection and tracking.
Electronic Warfare (EW): M-type tubes are used in electronic warfare systems for jamming enemy radars and communication signals. Their high power output helps to overpower and disrupt enemy electronics.

How to Calculate RF Output Power?

RF Output Power calculator uses RF Output Power = RF Input Power*exp(-2*RF Attenuation Constant*RF Circuit Length)+int((RF Power Generated/RF Circuit Length)*exp(-2*RF Attenuation Constant*(RF Circuit Length-x)),x,0,RF Circuit Length) to calculate the RF Output Power, RF Output Power formula is defined as the amount of microwave energy emitted by a device typically after amplification by a tube. It's calculated by combining the initial radio frequency power entering the device (Pin) with the additional radio frequency power generated within the device itself (Pgen). RF Output Power is denoted by P_out symbol.
