GaAs Varactor Diodes Abrupt Junction ® TM 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 Description ● High Q Tunable Filters ● Phase Shifters ● Pre-Selectors 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. Maximum Ratings Reverse Voltage Breakdown Voltage Forward Current 50 mA @ 25°C Incident Power +20 dBm @ 25°C Operating Temperature -55°C to +175°C Storage Temperature -55°C to +200°C IMPORTANT: For the most current data, consult our website: www.MICROSEMI.com Specifications are subject to change. Consult factory for the latest information. 1 The MV20000 Series of products are supplied with a RoHS complaint Gold finish . These devices are ESD sensitive and must be handled using ESD precautions.
