These super hyperabrupt varactor diodes are ideal for tuning LC resonant circuits from video frequencies through VHF with frequency ratios as high as 4 to 1. They are also ideal for wide deviation voltage controlled oscillators and voltage controlled crystal oscillators. Two volt capacitance values range from 57 to 350 pF are offered in this designer-oriented family. These diodes feature exceptionally large capacitance ratios, very high Q, straight-line frequency performance over a 1.5 to 4 volt tuning range.
