PRODUCT Data Sheet: EtherHelix™ GPS Part No. 1002857 EtherHelix Mission Critical GPS Antenna 1.575 GHz RHCP KEY BENEFITS DESIGN ADVANTAGES EtherHelix™ series of Isolated Magnetic Dipole™ (IMD) GPS antennas deliver on the key needs of device designers for higher functionality and performance. EtherHelix are the world’s smallest, stand-alone, circular polarized, external /internal GPS antennas. These innovative antennas provide compelling advantages for GPS enabled cell phones, navigation equipment, and other mobile devices. TECHNOLOGY ADVANTAGES Real-World Performance and Implementation Antennas may look alike on the outside, but the important difference is inside. Other antennas may contain simple PiFA or monopole patch 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. Best in Class Performance—Smallest Occupied Volume  Reduced size and weight results in simpler integration.  High selectivity minimizes the need for additional filters.  IP68 —UV stabilized. High Tolerance to Frequency Shifts  IMD’s high RF isolation resists antenna de-tuning that can otherwise impair reception. 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  Lower axial ratio results in improved signal reception, providing 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  EtherHelix antennas are supported by our experienced 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.
