MULTIFUNCTIONAL MICROWAVE DEVICE Russian patent published in 2011 - IPC H03B19/14 

FIELD: electricity.

SUBSTANCE: multifunctional microwave device, comprising two transfer lines with identical wave resistances, one of which is intended for input of microwave signal, the other one - for output, two identical reservoirs. At the same time one end of the first reservoir is connected to end of transfer line at the input, the other end - to gate of field transistor with Schottky barrier and one end of resistor, the other end of resistor is connected to one end of the first inductance, one end of the second reservoir is connected to transfer line at the output, and the other one - to drain of field transistor with Schottky barrier, via the second inductance constant positive voltage is sent to this drain, is equipped with the second field transistor with Schottky barrier and two inductances - third and fourth ones. Drains of both field transistors with Schottky barrier are connected to each other. Source of the second field transistor with Schottky barrier is connected to the other end of the first inductance, and its gate is connected to source of permanent control voltage. One end of third inductance is connected to the other end of the first reservoir, and its other end is grounded. One end of fourth inductance is connected to source of the first field transistor with Schottky barrier, and its other end is grounded.

EFFECT: expansion of functional capabilities, with preservation of working frequency range.
