Description and Applications

M/A-COM’s

MA4ST1300

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 100% matte Sn plating on our

RoHs compliant equivalent devices.
