Description
These silicon - glass PIN diode chips are fabricated with
M/A-COM’s patented HMIC process. They contain a single
shunt silicon PIN diode embedded in a glass substrate with dual
75 x 150 micron bond pads located near the chip edges. The large
pads allow use of multiple bond wires. The location of these pads
on a glass substrate results in low parasitic capacitance. The
diode junction is passivated with silicon nitride and a layer of
polyimide has been added for scratch protection during assembly.
The devices are available on industry standard tape frame for
automatic insertion and assembly in high volume applications.
Applications
These diodes are designed for use as general PIN elements in
switches and switched pad attenuators. The chips can handle up
to 10 watts of RF power, and are well suited for use in T/R
switches for subscriber phones, particularly the higher power and
higher frequency systems for satellite based systems. They are
also useful for the switching element in phased array radar appli-
cations. The larger bond pad allows for two (2) 1 mil dia contact
wires which reduces the bond wire inductance almost in half.
