MNS Microwave Chip Capacitors MA4M Series MA4M Series MNS Microwave Chip Capacitors Features Excellent Repeatability (Wafer-to-Wafer and Lot-to-Lot) Small Size Low Loss, High Q Available with Round or Square Bonding Pads Case Style Description M/A-COM’s MA4M series of MNS (metal-nitride-silicon) silicon chip capacitors is designed specifically for high reliability and repeatable performance in microwave circuit applications. These capacitors are made using a low pressure chemical vapor deposition (LPCVD) that results in dense, uniform nitride layers. These capacitors exhibit higher capacitance per unit area (resulting in smaller chip size) than 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 of 150ºC. 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, capacitive loads and tuning elements in oscillators, multipliers and filters. 350 Comparison of M/A-COM MNS Capacitors to Ceramic Chip Capacitors Characteristics Compared Operating Temperature Range Temperature Coefficient Insertion Loss of a 20 pF Capaci...
