PRODUCT Data Sheet: GPS

Part No. M420110

Savvi TM Embedded

Ceramic GPS Antenna

1.575 GHz

KEY BENEFITS

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.

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.

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

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.

www.ethertronics.com/resources/.

? 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 implementation— no matching networks .

RoHS Compliant

? Antennas comply with appropriate RoHS Directives.

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.

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.
