DESCRIPTION
The VJ 3505 multi-layer ceramic chip antenna is a small
form-factor, high-performance, chip-antenna designed for
TV reception in mobile devices in the UHF band. It allows
mobile TV device manufacturers to design high quality
products that do not bear the penalty of a large external
antenna.
manufacturing technologies, this product complies with the
MBRAI standard while maintaining a small outline.
Focusing on consumer applications, the antenna is designed
to be assembled onto a PC board in the standard reflow
process.
Target customers of the VJ 3505 are mobile phone makers,
portable multimedia device makers, notebook OEMs and
ODMs, and accessory card OEMs and ODMs.
