MICROWAVE CHIP RESISTORS
MSMW
Mini-Systems, Inc.
Top Contact Microwave Chip Resistor
series is designed to fit a wide variety of applications operating in the Microwave Bands. All
sizes offer the
high stability, flat frequency response
and
low noise
of Mini-Systems, Inc. Thin Film materials.
Specialized LASER trim
techniques
specifically designed for this series guarantee operation up to
40 GHz.
Microwave Chip Resistors can be attached to associated circuitry through ribbon
or wire bonding, conductive epoxy, soldering to terminations or mounted as flip-chips.
