Characteristics of an area-variable varactor diode

IEEE Transactions on Microwave Theory and Techniques, 1996
Photoresponses and microwave characteristics of an area-variable varactor diode are investigated in the frequency range of 1-7 GHz. The on/off ratio of the capacitance as large as 18.5 at 1 GHz is demonstrated and it is shown that the ratio strongly depends upon the access resistance between the cathode and the floating contacts. The capacitance of the

Planar varactor diode development

17th International Conference on Infrared and Millimeter Waves, 2017
ill./ A.F.AL11.11,16...1,1,11 Schottky barrier varactor diodes are used as frequency multipliers to supply local oscillator power for heterodyne receivers at millimeter and submillimeter wavelengths. Whisker contacted diodes have been developed which generate sufficient power at frequencies as high as 700 GHz for ground based and airborne experiments ...

Generalized mathematical model of the varactor diode

2003 Siberian Russian Workshop on Electron Devices and Materials. Proceedings. 4th Annual (IEEE Cat. No.03EX664), 2004
This paper considers a generalized mathematical model of a varactor diode, taking into account the effect of charge accumulation in the base of the diode, and the nonlinear dependency of the consequent diode resistance from its associated voltage.

THE SELECTION OF VARACTOR DIODES FOR A 2X MULTIPLIER

1963
Abstract : A simplified procedure is presented for the selection of varactor diodes in frequency multiplier design. Graphs are presented that enable the circuit designer to select the proper diode to fulfill the design objective.
