Description and Applications
The MA4E2054 series are low barrier N-type silicon
Schottky diodes assembled in surface mount plastic
packages. They are designed for use as high
performance mixer and detector diodes.
The MA4E20541-1141T (SOD-323), MA4E20541-1279T
(SC-79) and MA4E2054A1(SOT-23) are single
element Schottky diodes characterized for use as
single ended mixers and detectors. The
MA4E2054B1 and MA4E2054D1 (available in both
the SOT-23 and SOT-323 packages) incorporate
two Schottky chips in series pair configurations.
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 identification and toll collection.
