SERVICE AND SUPPORT
Extensive RF Experience
Our Savvi ceramic antennas are supported by exten-
sive application notes, and when needed, by the
expertise of RF engineers who have integrated
hundreds of antenna designs into wireless devices.
Global Operations & Design Support
Ethertronics’ global operations encompass an
integrated network of design centers that provide
local customer support.
Ethertronics’ Savvi series of Isolated Magnetic
Dipole™ (IMD) antennas deliver on the key needs of
device designers for higher functionality and
performance in smaller/thinner designs. These
innovative antennas provide compelling advantages
for GPS enabled cell phones, navigation equipment,
and other mobile devices.

END USER ADVANTAGES
Superior Range
Greater antenna efficiency means longer range and
a better end user experience.
Exceptional Coverage
Better coverage results in improved performance
while inside buildings, cars or other areas where
signal reflection occurs.
Faster Acquisition Times
Users experience faster signal acquisition for GPS
readings.
DESIGN ADVANTAGES
Best in Class Performance—Smallest Occupied Volume
Powerful combination of 63% peak efficiency and
simple implementation guidelines.
Minimal ground clearance and component “keep
out” area. Very low component height.
High selectivity eliminates the need for additional
filters and frees up board space.
High Tolerance to Frequency Shifts
IMD’s high RF isolation resists antenna de-tuning that
can otherwise impair reception.
Single part works for various PCB sizes and layouts.
Quicker Time-to-Market
Fewer design changes.
Simpler implementationno matching networks.
RoHS Compliant
Antennas comply with appropriate RoHS Directives.

TECHNOLOGY ADVANTAGES
KEY BENEFITS
Part No. M420110
Real-World Performance and Implementation
Ceramic antennas may look alike on the outside, but
the important difference is inside. Other antennas
may contain simple PiFA or monopole designs that
interact with their surroundings, complicating
component layout or changing performance with use
position. Ethertronics’ antennas utilize patented IMD
technology to deliver a unique size and performance
combination.
Stays in Tune
High RF isolation means
IMD antennas resist
detuning regardless of
usage position. And one
standardized part can
typically be placed in a
variety of locations.
Smallest Effective Size
IMD antennas require a
smaller keep-out area for surrounding components,
leading to a smaller effective size.
High Performance
IMD’s high efficiency and simple design rules lower
development risk and speed time-to-market without
sacrificing performance. Plus, high RF selectivity
eliminates the cost and space for band-pass circuitry.
