Overview
Low-Voltage / High Q Si Hyperabrupt Varactors MA4ST200 Series MA4ST200 Series Low-Voltage / High Q Si Hyperabrupt Varactors Features • • • • • • • Surface Mount Packages (SOT-23, SOT-323, SOD-323) High Q at Low Voltages High Capacitance Ratio at Low Voltages SPC Process for Superior C-V Repeatability Available as Single and Common Cathode Pairs Tape and Reel Packaging Designed for Commercial Wireless Applications Configurations TOP VIEW (SOT-23, SOT-323) Description M/A-COM’s MA4ST200 series is a ion-implanted, hyperabrupt junction, silicon tuning varactors in SOT-23, SOT-323, and SOD323 surface mount packages.
This series of varactors is designed for high Q and low voltage operation.
Each varactor type has a Q greater than 400 at -2 V.
Single TOP VIEW (SOD-323) Double Applications The MA4ST200 series tuning varactors are useful for wide band tuning and low phase noise applications where the supply voltage is limited to 5 volts or less.
These varactors have been specifically designed for use in the wireless communications up to the 2.
4 GHz band.
Applications include VCOs and voltage tuned filters.
