Dual Diode - Common Cathode Configuration: MACOM's MA4ST1200 series is a highly repeatable, UHCVD/ion-implanted, hyper abrupt 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, 3 Lead. These diodes are offered with standard Sn/Pb plating, as well as with 100% matte Sn plating on our RoHS compliant equivalent devices.
