Description and Applications
The MA4E2054 series are low barrier n-type silicon
Schottky diodes assembled in low cost surface
mount plastic packages. They are designed for use
as high performance mixer and detector diodes.
These parts are offered with Sn/Pb plating, as well
as with 100 % matte S n plating on the RoHS compliant part
numbers.
The MA4E2054 -1141T (SOD-323), MA4E20541 -1279
(SC-79) and the MA4E2054A and MA4 E 2054C
(available in both the SOT-23 and SOT-323 packages) are
single element Schottky diode s characterized for use
as single ended mixers and detectors. The
MA4E2054B and MA4E2054D (available in both the
SOT-23 and SOT-323 packag es) incorporate two
Schottky chips in series pair configurations. The
MA4E2054E-1068T consis ts of two Schottky chips in
the SOT-143 package in an unconnected pair
configuration. These diodes are useful for balanced
mixer and detector voltage doubler circuits. Applications for
the MA4E2054 series include VSAT and DBS mixers. The
small diode package size and low cost make them
attractive for use in RF tag applications for identifica-
tion and toll collection.
