| KV2001 - KV2801 TM (R) VARACTOR DIODES HF/VHF/UHF Hyperabrupt Junction RoHS Compliant DESCRIPTION These families of hyperabrupt junction RF varactor diodes feature computer controlled grown junction epitaxy which provides extraordinary consistency and the highest Q available in a 22 Volt hyperabrupt varactor. These series give the designer a full capacitance range of 10 to 500 pF at 3 or 4 volts of bias, depending on product series. They allow octave tuning of LC tanks through 500 MHz. With a reduced 1.5 to 1 frequency ratio, straight-line-frequency tuning over a 3 to 8 volt tuning range is possible. Ultrahigh Q and excellent large signal handling capabilities, along with a 2 to 1 capacitance ratio, is obtained by tuning from 9 to 20 volts of reverse bias. Linear, wide deviation tuning of VCXO/TCXO'S and frequency modulators also results when these diodes are tuned over a 3 to 8 volt bias range. Closely matched sets of all HF-VHF diodes are available along with "A" suffix versions having 5% capacitance tolerance at 3 or 4 volts of reverse bias depending on series selected. KEY FEATURES Available as packaged devices or as chips for hybrid applications Octave Tuning Range Ultrahigh Q Available with 5% Tolerance CT www.MICROSEMI.com APPLICATIONS These families of hyperabrupt varactors are ideal for wide bandwidth VCOs. They also provide excellent performance in frequency modulators, voltage variable filters, analog phase shifters, TCXOs and VCXOs. APPLICATIONS/BENEFITS Values cover the entire HF / VHV / UHF spectrum; Highest Q / lowest VCO phase noise Tough MIL-Spec SiO2 passivation Dozens of package outlines available ABSOLUTE MAXIMUM RATINGS AT 25 C (UNLESS OTHERWISE SPECIFIED) Rating Maximum Working Voltage Storage Temperature Operating Temperature Symbol VR TSTG TOP Value 22 -65 to +150 -55 to +150 Unit V KV2001-KV2801 KV2001-KV2801 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.
