PRODUCT DATA SHEET: BLUETOOTH ?

Part No. M420310

Savvi TM Embedded Ceramic

Bluetooth Antennas

2.4—2.5 GHz

KEY BENEFITS

DESIGN ADVANTAGES

Best in Class Performance—Smallest Occupied Volume

? Powerful combination of 63% peak efficiency and sim-

ple implementation guidelines.

? Minimal ground clearance and component “keep

out” areas. Very low component height.

? High selectivity eliminates the cost for additional

filters and frees up board space

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 Bluetooth ? enabled cell phones, media players

and other mobile devices.

TECHNOLOGY ADVANTAGES

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.

Ethertronics’ antennas utilize patented IMD

technology to deliver a unique size and performance

combination.

Stays in Tune

High RF isolation means

IMD antennas resist de-

tuning 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 Tolerance to Frequency Shifts

? IMD’s high RF isolation resists antenna detuning that

otherwise impair reception.

? Single part works for various PCB sizes and layouts.

Quicker Time-to-Market

? Fewer design modifications required to pass RF

test suite.

? Simpler implementation— no matching networks .

RoHS Compliant

? Ethertronics’ antennas comply with the European RoHS

Directive 2002/95/EC.

END USER ADVANTAGES

Superior Range

? Greater antenna efficiency means longer range and

a better end user experience.

Exceptional Coverage

? Better coverage delivers more reliable wireless

connections for mobile phones, laptops, stereo

headsets, cars, media players, audio systems

and more.

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

High Performance

IMD’s high efficiency and simple design rules lower

development risk and speed time-to-market without

Ethertronics’ global operations encompass an

integrated network of design centers that provide

local customer support.

sacrificing performance. Plus, high RF selectivity

eliminates the cost and space for band-pass circuitry.
