Description and Applications
The 4M series of MNS (metal-nitride-silicon) chip capacitors
is designed specifically for high reliability and repeatable
performance in microwave circuit applications. These ca-
pacitors are made using a low pressure chemical vapor
deposition (LPCVD) that results in dense, uniform nitride
layers. These devices exhibit higher capacitance per unit
area (resulting in smaller chip size) and improved rugged-
ness over similar MOS, MIS and ceramic capacitors.
Evaporated gold contacts are used to provide an easily
bondable metal pad on the capacitor chip. M/A-Com MNS
capacitors have shown no measurable capacitance change
when subjected to the rated standoff voltage at 150
Degrees C.
The MA4M series of chip capacitors is an excellent choice
for use in hybrid microwave circuits up through Ku-band,
where low loss, high reliability, small size and temperature
stability are prime concerns.
These chip capacitors are suited for applications requiring
DC blocks, coupling capacitors, bypass capacitors, capaci-
tive loads and tuning elements in oscillators, multipliers and
filters.
