Description
M/A-COM’s MA4ST1200 series is a highly repeatable,
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, 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.
