**Legacy P/N: 2440AT62A0085** 

## **P/N: 2440AT62A0085001U** 

## **2.44 GHz RF Chip Antenna** 

- 2.4 – 2.485 GHz Operational Frequency 

- Bluetooth, WLAN 

- SMD, patch, 12x12x4mm (LxWxT) 

- Can be mounted in the center, corner or edge 

- Linear polarization 

- RoHS compliant 

Johanson Technology, Inc. (JTI) miniature RF ceramic chip antennas are made using Low Temperature Co-fired Ceramic (LTCC) technology which has the ability to embed low and high dielectric constants inside our antenna. This enables our components to have high detuning resilience and stability over extreme temperatures (~2ppm).

## **Recommended Mounting Configuration 2 (Evaluation Board Unavailable)** 

We have conducted internal studies to show that the following corner or edge placements provide antenna efficiency results with minimal detrimental effects. 

We recommend that the antenna be mounted >3mm from any PCB edge.
