Surface Mount Ceramic Chip Antennas for 2.4 GHz
VJ5105W240GXCMT chip antenna
The VJ5105W240 series are small form-factor,
high-performance chip-antennas designed to be used in
wireless, bluetooth and ISM band 2.4 GHz.
The VJ5105W240 series present an excellent performance
(max. gain 2.1 dBi) with a low profile needed in most wireless
applications.
DESCRIPTION
The VJ5105W240GXCMT 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.
FEATURES
• Ultre small outline (3.2 mm x 1.6 mm x 1.2 mm)
• 50
unbalanced tuning interface
•Omnidirectional
• Assembled onto a PCB in the standard reflow process
• Low profile for thin type terminal
• High stability in temperature / humidity changes
• High mechanical strength
• Wide operating temperature range (- 40 °C to + 85 °C)
• Material categorization: For definitions of compliance
