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.
