Low - Voltage / Wide Band Si Hyperabrupt Varactors MA4ST300 Series MA4ST300 Low - Voltage / Wide Band Si Hyperabrupt Varactors Features - - - - - - - - Surface Mount Packages (SOT-23, SOT-323, SOD-323) High Capacitance Ratio at Low Voltages High Q at Low Voltages SPC Process for Superior C-V Repeatability Available as Single and mon Cathode Pairs Tape and Reel Packaging Designed for mercial Wireless Applications Configurations TOP VIEW (SOT-23, SOT-323) Description The MA4ST300 series are ion-implanted, hyperabrupt junction, silicon tuning varactors in SOT-23, SOT-323, and SOD-323 surface mount packages. This series of varactors is designed for high capacitance ratio and low voltage operation. Each varactor type has a better than 3:1 capacitance ratio between 0.5V and 3.0V. Single TOP VIEW (SOD-323) Pair Applications The MA4ST300 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 to cover wireless application bands up to the 2.4 GHz WLAN band. Applications include VCOs and voltage tuned filters.
