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 tuning and low phase noise application where the supply voltage 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 SOD323 configurations with Common Cathode version offered in a 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.

Mounting Information
The illustration indicates the recommended mounting pad configuration for the SC-79, SOT-323 and SOD-323 packages. Solder paste containing flux should be screened onto the pads to a thickness of 0.005- 0.007 inches. The plastic package is placed in position, firmly adhering to the solder paste. Permanent attachment is performed by a reflow soldering procedure during which the tab temperature does not exceed +275 C and the body temperature does not exceed +250 C, for standard models and +260 C for the RoHS compliant devices. Please refer to Application Note M538 for surface mounting instructions.
