Passive Components: MMI 300 Series
Passive Components
Spiral Inductors
Description The MicroMetrics MMI 300 series of Spiral Inductors are formed by photolithography and plating techniques on quartz substrates. They eliminate the need for hand forming and ”staking“ of coil in hybrid circuits. They provide uniformity, durability and repeatability in circuit fabrication. The coils are polyimide coated to protect from ambient contaminants, and to eliminate the need for conformal coating. Quartz substrates are rugged and reduce dielectric losses. Chips may be bonded using either conductive or non conductive epoxies, and wire bonded with gold wire or ribbon by thermocompression bonding. Features No Need for ”Staking“ Coil Passivated Protective Coating Over Coil Dimensional Uniformity Planar Solid Structure Coil Packaging Chip

Applications The Spiral Inductors are ideally suited for bias injection into oscillators, amplifiers and microwave switchesDataSheet4U.com (bias tees). They can also be used to bias tuning varactors, PIN diodes, GOLD BONDING PADS
transistors and monolithic circuits.
