Description and Applications
M/A-COM’s MA4ST2000 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 capaci-
tance ratio for low battery voltage operation. It is effi-
cient for wide band tuning and low phase noise appli-
cation where the supply voltage is limited to 5 volts or
less. Varactors in this series have a typical 18:1 ca-
pacitance ratio between 0.1 V and 4.7 V and a 12:1
ratio between 0.1 V and 2.7 V. The Varactors are of-
fered as Singles in both SC-79 and SOD-323 configu-
rations with Common Cathode version offered in a
SC-70, 3 Lead. These diodes are offered with stan-
dard Sn/Pb plating , as well as 100% matte Sn plating
on our RoHs compliant equivalent devices.
