The 4M series metal nitride silicon chip capacitors are specifically designed for high reliability and repeatability in microwave circuit applications. These capacitors are fabricated using low-pressure chemical vapor deposition (LPCVD), which enables the formation of a dense and uniform nitride layer. Compared to similar MOS, MIS and ceramic capacitors, these devices have higher unit area capacitance (resulting in smaller chip size) and greater durability. Evaporated gold contacts are used to provide easily adhered metal pads on the capacitor chip. The M/A-Com MNS capacitors show no measurable capacitance change under the rated isolation voltage of 150 degrees Celsius.
The MA4M series chip capacitors are the optimal choice for Ku-band hybrid microwave circuits. In the Ku-band, low loss, high reliability, small size and temperature stability are the primary considerations.
These chip capacitors are suitable for applications that require DC blocks, coupling capacitors, bypass capacitors, capacitor loads and tuning elements in oscillators, multipliers and filters.
