This document introduces the features and characteristics of M/A-COM's MA4M series MNS microwave chip capacitors, including excellent repeatability, small size, low loss, and high Q. These capacitors are made using low-pressure chemical vapor deposition technology, resulting in dense and uniform nitride layers. They have higher capacitance per unit area compared to similar MOS, MIS, and ceramic capacitors, resulting in smaller chip size. Evaporated gold contacts are used to provide easily bondable metal pads on the capacitor chip. M/A-COM MNS capacitors have shown no measurable capacitance change when subjected to the rated standoff voltage of 150°C. The MA4M series chip capacitors are an excellent choice for hybrid microwave circuits up to Ku-band, offering advantages of low loss, high reliability, small size, and temperature stability. They are suitable for applications requiring DC blocks, coupling capacitors, and more.
The M/A-COM MA4M series consists of metal-nitride-silicon (MNS) silicon chip capacitors designed for high reliability and repeatable performance in microwave circuit applications. These components are manufactured using low pressure chemical vapor deposition (LPCVD) to create dense, uniform nitride layers, offering higher capacitance per unit area compared to similar MOS, MIS, or ceramic capacitors.
