I'm looking for replacement of Hyperabrupt varactor diode MV1404 and MV1401 speitally some thing cheeper I need some thing with Capacitance ratio of 10+
The doping profile in this diode is optimized for the removal of the stored charge to end in a rapid dq/dt. Stored charge is generated in forward bias and removed in reverse bias. This sudden stopping of the reverse current causes a current waveform with large amplitude levels of the higher harmonics. This diode is used in frequency multipliers commonly called comb generators from the graphical shape of the graph of the frequency spectrum.
