GaAs Varactor Diodes TM ® Abrupt Junction MV20001 – MV21010 Features ● ● ● ● ● ● High Q Values for Higher Frequency Performance Constant Gamma Design Low Reverse Current Available as Chip or Packaged Diodes Available in Chip-on-Board Packaging Custom Designs Available Applications ● ● ● ● ● VCOs Phase-Locked Oscillators High Q Tunable Filters Phase Shifters Pre-Selectors Description Microsemi’s GaAs abrupt junction varactors are fabricated from epitaxial layers grown at Microsemi using Chemical Vapor Deposition. The layers are processed using proprietary techniques resulting in a high Q factor and very repeatable tuning curves. The diodes are available in a variety of microwave ceramic packages or chips for operation from UHF to millimeter wave frequencies. Breakdown Voltage 50 mA @ 25°C +20 dBm @ 25°C -55°C to +175°C -55°C to +200°C Maximum Ratings Reverse Voltage Forward Current Incident Power Operating Temperature Storage Temperature 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 The MV20000 Series of products are supplied with a RoHS complaint Gold finish .
