摘要： A memory device comprising a circuit including in combination a gate diode and an oscillatory loop having a pulse generating diode. The oscillatory loop is adapted to produce a pulse train to be stored and to cease oscillate respectively in response to application thereto of a single and negative trigger pulse when the pulse generating diode is biased at a voltage between the oscillation starting and terminating voltages of the diode. With a reading-out pulse being applied to the loop, a single pulse or a pulse train is obtained from the stored pulse train. The pulse generating diode employed in the device is a novel having a Nu N structure.

摘要： The coaxial line circuit for an avalanche diode noise generator is disclosed. The coaxial line circuit includes a short at one end thereof with the avalanche diode connected in series with the inner conductor at the shorted end of the coaxial line. The short preferably includes a block of thermally conductive material closing off the end of the coaxial line with one terminal of the diode being connected to the block for heat sinking the diode. In addition, the shorting block includes a portion concentric to and axially coextensive with the end portion of the outer conductor of the transmission line to form a relatively high capacitance between the outer conductor and the shorting block. This capacitance stores the energy for the relaxation oscillator mode of the avalanche diode which is preferably operated as a noise generator. In another embodiment, a wave-reflective member is placed within the coaxial line a distance from the shortcircuited end thereof to produce a subharmonic cavity for increasing the power density of the noise spectrum output at higher harmonics of the cavity. In another embodiment, a varactor diode is placed in the coaxial transmission line at a point of maximum electric field of the output mode for tuning the output frequency of the noise.
