Description
The MA4E2099-1284 Bridge Octoquad is offered
for high dynamic range applications. This device is
constructed with Silicon High Barrier Schottky Di-
odes fabricated with the patented Heterolithic Mi-
crowave Integrated Circuit (HMIC) process to en-
sure electrical characteristics uniformity for each
junction. HMIC circuits consist of Silicon pedestals
which form diodes or via conductors embedded in
a glass dielectric, which acts as a low dispersion,
low loss, microstrip transmission medium.
The
combination of silicon and glass allows HMIC de-
vices to have excellent loss and power dissipation
characteristics in a low profile, reliable device.
Applications
The device can be used in high power mixer, de-
tector, and limiter circuits through 12 GHz.
