M830120

**DATASHEET** Part No. M830120 Product: 1.575GHz Ceramic Antenna 

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 a GPS enabled handheld devices, media players and other mobile devices. 

## **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. 

## **Greater Flexibility** 

Ethertronics’ first-in-class IMD technology enables you to develop concept designs that are more advanced and that deliver superior performance in reception critical applications. 

## **Electrical Specifications** 

## **KEY BENEFITS** 

## **Stay-in-Tune** 

IMD antenna technology provides superior RF field containment, resulting in less interaction with surrounding components. 

**Quicker Time-to-Market** 

By optimizing antenna size, performance and emissions, customer and regulatory specifications are more easily met. 

## **Reliability** 

Fully compliant with the European RoHS Directive 2011/65/EU.
