Description

technical field

[0001] The present invention relates to the power synthesis technology used in the microwave and millimeter wave frequency bands, in particular to the radial power of a broadband air microstrip structure with high isolation (the coupling coefficient between ports is less than -20dB and can be called high isolation) Synthetic amplifier. Background technique

[0002] In the microwave high-end and millimeter wave frequency bands, with the increase of frequency, the size of semiconductor solid-state devices decreases, the power capacity decreases, and the output power of a single device is difficult to meet the needs of communication electronic systems. People have proposed the power synthesis of multiple solid-state devices. way to realize high-power solid-state power devices. The properties of the power combining network directly determine the properties of the combining amplifier. Therefore, the key to the power combining technology is the nature of the power...
