Description
M/A-COM’s MA4ST1200 series is a highly repeat-
able, UHCVD/ion-implanted, hyperabrupt silicon tun-
ing varactor in a cost effective surface mount pack-
age. 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.
