M420310

PRODUCT DATA SHEET: BLUETOOTH® Part No. M420310 SavviTM Embedded Ceramic Bluetooth Antennas 2.4—2.5 GHz KEY BENEFITS DESIGN ADVANTAGES 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 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. More information is available on our Website at www.ethertronics.com/resources/. Best in Class Performance—Smallest Occupied Volume • Powerful combination of 63% peak efficiency and simple 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 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 extensive 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.
