APPLICATIONS
DESCRIPTION
• ISM band 2.4 GHz wireless applications
The VJ5104W240GXCMT ceramic chip antenna is a small
form-factor, high-performance, chip-antenna designed for
operation at 2.4 GHz. It allows manufacturers to design high
quality products that do not bear the penalty of a large
external antenna, and is designed to be assembled onto a
PC board using a standard reflow process.
