A push-pull transferred-electron oscillator circuit in which a number of transferred-electron devices are connected in parallel to a DC bias circuit, but, in the RF (radio frequency) circuit, they operate in a push-pull manner so that the RF power is increased by four times for the same ...
Push-pull electron tubePush-pull electron tubeThis invention relates to electron tubes and more especially to electron tubes for use in ultra high-frequency circuits. A principal object of the invention relates to an electron tube of the duplex or push-pull pentode type for use in ultra high-...
A pair of transferred-electron devices, such as Gunn diodes, are spaced apart in a hollow microwave conductor operating in a TE or TM mode. The Gunn devices are coupled in energy exchanging relation to the fields of the operating mode and are spaced apart by approximately an integer number ...
