MA4ST1200 Series Low Tuning Voltage / Low Rs Silicon Hyperabrupt Rev. V10 Varactor Diode Features Package Styles Low Series Resistance Low Tuning Voltages High Capacitance Ratio Low Tuning Voltages SOD-323 Surface Mount Plastic Packages: SC-70 (3 lead) SC-79, SOD-323, SC-70 (3L) SPC Process for Superior C vs. V Repeatability RoHS* Compliant Description The MA4ST1200 series is a highly repeatable, SC-79 UHCVD/ion-implanted, hyperabrupt silicon tuning varactor in a cost effective surface mount package. This series of varactors is designed for high capacitance ratio, and high Q for low battery voltage operation. It is efficient for wide band tuning and low phase noise application where the supply voltage is limited to 5 volts or less. The varactors are offered as singles in SC-79, and SOD-323 along with a common cathode version offered in the SC-70 (3L). These diodes are offered with 100% matte Sn plating.
