Description
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 at frequencies from VHF through low Ku band.
The MA4E2054-1141T (SOD-323), and the MA4E2054A and
the MA4E2054C (available in both the SOT-23 and SOT-323
packages) are single element Schottky diodes characterized for
use as single ended mixers and detectors. The MA4E2054B and
MA4E2054D (available in both the SOT-23 and SOT-323
packages) incorporate two Schottky chips in series pair
configurations. The MA4E2054E-1068T consists 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 identification and toll collection.
The part number consists of the base chip (MA4E2054),
followed by the wiring configuration (A, B, C, D, E, omit for
SOD-323), the package style (287, 1068, 1141, 1146) and a “T”
for tape and reel.
The MA4E2054-1141T is available only in the SOD-323
package style. The MA4E2054A , B, C, D are available in both
the SOT-23 and SOT-323 package styles. The MA4E2054E is
available only in the SOT-143 package style.
