| KV1401 - KV1801 TM (R) VARACTOR DIODES HF/VHF Super Hyperabrupt Junction RoHS Compliant 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 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. 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 RoHS 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 RoHS compliant. Please consult the factory for ordering information for the RoHS 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 Compliant 1 www.MICROSEMI.com 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 Modulators ABSOLUTE MAXIMUM RATINGS AT 25 C (UNLESS OTHERWISE SPECIFIED) Rating Maximum Working Voltage Storage Temperature Operating Temperature Symbol VR TSTG TOP Value 12 -55 to +125 -65 to +200 Unit V Preselectors KV1401-KV1801 KV1401-KV1801 C C IMPORTANT: For the most current data, consult our website: www.MICROSEMI.com Specifications are subject to change. Consult factory for the latest information. These devices are ESD sensitive and must be handled using ESD precautions. 1 Unless otherwise specified, these products are supplied with Gold terminations suitable for RoHS compliant assembly.
