CENTIMETRE-RANGE MICROWAVE TRANSMITTER Russian patent published in 2013 - IPC H04B1/00 H03B9/08 

FIELD: radio engineering, communication.

SUBSTANCE: centimetre-range microwave transmitter has a decoupling device, a p-i-n attenuator, a microwave amplifier, a load, a power supply and a modulator, as well as a waveguide for feeding the input microwave signal, a frequency code decoder, a connector pin for feeding the carrier-frequency code, a connector pin for connecting a mechanical interface, a connector pin for feeding commands for switching on-board radar modes. The frequency code decoder includes series-connected matching device, control device, digital-to-analogue converter (DAC), controlled current source, and the microwave amplifier includes series connected first travelling-wave tube (TWT1), intermediate path, second travelling-wave tube (TWT2), output path.

EFFECT: providing maximum output power of the centimetre-range transmitter at carrier frequencies by using two travelling-wave tubes and providing optimum matching of operating modes thereof.
