Description and Applications
The MA4E2054L-1261 diode is a low barrier, n-type,
silicon Schottky device.
It is useful as a high
performance mixer or detector diode at frequencies
from VHF through X-band.
These chips can be
used in automatic assembly processes due to their
0.004” gold bond pads and sturdy construction.
