**P/N: 2450AT07A0100002T Legacy P/N: 2450AT07A0100T-AEC** 

## **2.44 GHz RF Chip Antenna** 

- 2.4 – 2.48 GHz pass band 

- Bluetooth, WLAN 

- Ultra-Miniature SMD, EIA 0402 

- Mid-edge mount 

- RoHS compliant and AEC-Q200 Qualified 

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).

*Note: Ground Vias are highly recommended to have better antenna efficiency. 

If you’d like the CAD PCB layout or have any questions, contact our application engineers at https://www.johansontechnology.com/ask-a-question 

> 4 It is recommended that the designer leave available slots for a "pi" (or shunt-series-shunt) network. The antenna matching network values above are used when antenna is mounted on Johanson's evaluation board. The matching values on client’s PCB will be different, depending on the layout, thickness, material, etc. Go to: https://www.johansontechnology.com/tuning and see how to obtain the new values.
