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 capacitance ratio for low
battery voltage operation. It is efficient for wide band tun-
ing and low phase noise application where the supply volt-
age is limited to 5 volts or less. Varactors in this series
have a typical 18:1 capacitance 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 offered as Singles in both SC-79 and SOD-
323 configurations 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.
