The Massachusetts Bay Technologies MSI series of Spiral Inductor chips are formed by plating and photo/ etch techniques on quartz substrates. These devices are designed to meet hybrid microwave circuit requirements through Ku band. They eliminate the need for hand forming and “staking” coil in hybrid circuits.
Spiral inductors are used for bias injection into oscillators, amplifiers and microwave switches (bias tees). They can also be used for bias tuning Varactor diodes, PIN diodes, transistors, and monolithic circuits.
