.Data Sheet.co.kr KV1401 - KV1801 TM ® VARACTOR DIODES HF/VHF Super Hyperabrupt Junction Ro HS pliant DESCRIPTION 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 p F 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. They are also available in closely matched sets as well as tight Ct tolerance options. Consult the factory for details. The standard Super Hyperabrupt series of devices meet Ro HS requirements per EU Directive 2002/95/EC, including the discrete chip (style 00) and package styles 30 and 17. The standard axial device (style 11) is not Ro HS pliant. Please consult the factory for ordering information for the Ro HS version of the 11 style package. KEY Features - Available as packaged devices or as chips for hybrid applications - Octave Tuning Range - Ultrahigh Q - Tough MIL-Spec Glass Passivation - Precision Grown Junction Epitaxy - Available with 5% Tolerance CT - ROHS pliant 1 .MICROSEMI. APPLICATIONS Ultrahigh Q and excellent large signal handling capabilities, along with a greater than 10 to 1 capacitance ratio, is obtained by tuning from 2 to 10 volts of reverse bias. These diodes are well suited for linear, wide deviation tuning of VCXO/TCXO’S and frequency modulators as well as analog phase shifters, receiver preselectors, and active antenna matching units. APPLICATIONS/BENEFITS - HV-VHF VCO’s - TCXOs and VCXOs - Analog phase shifters - Frequency...
