Description
The MS8250 is a GaAs flip chip anti-parallel pair
Schottky device designed for use as harmonic mixer
elements at microwave and millimeter wave
frequencies. Their high cut-off frequency insures good
performance at frequencies to 100 GHz. Applications
include: transceivers, digital radios and automotive
radar detectors.
These flip chip devices incorporate Microsemi’s
expertise in GaAs material processing, silicon nitride
protective coatings and high temperature metallization.
They have large, 5 x 8 mil, bond pads for ease of
insertion. The MS8250 is priced for high volume
commercial and industrial applications.
