SERVICE AND SUPPORT
Extensive RF Experience
Our Savvi ceramic antennas are supported by exten-
sive application notes, and when needed, by the ex-
pertise 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.
These highly innovative antennas provide
competitive advantages for designers of cell phones,
laptops and other mobile equipment by combining
GPS & Bluetooth antennas in a single, highly compact
form factor suitable for the thinnest/smallest
devices. Ethertronics Isolated Magnetic Dipole (IMD)
technology utilizes superior RF isolation to combine
these two high performance antennas.

Embedded Ceramic
GPS & Bluetooth Antenna
1.575 and 2.4—2.5 GHz
END USER ADVANTAGES
Superior Range
Greater antenna efficiency means longer range.
Exceptional Coverage
Better GPS coverage means improved performance in
buildings, cars or other areas where signal reflection
occurs.
Better Bluetooth coverage means more reliable
wireless connections.
Faster Acquisition Times
Users experience faster signal acquisition for GPS
readings and Bluetooth connections.
DESIGN ADVANTAGES
Best in Class Performance—Smallest Occupied Volume
Over 80% peak efficiency for GPS and 60% Bluetooth.
Minimal ground clearance and component “keep out”
areas. Very low component height.
High selectivity eliminates the need for additional
filters and frees 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.

KEY BENEFITS
Part No. M442100
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 layout
or changing performance with use position. Ether-
tronics’ 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.
