Surface Mount Ceramic Chip Antennas for 1.575 GHz
VJ5101W157GXCMT chip antenna
The VJ5101W157 series are small form-factor,
high-performance chip-antennas optimized for GPS
applications.
Designed for GPS applications, the VJ5101W157GXCMT
antenna shows a superb performance and excellent peak/
average gain, allowing longer ranges than similar GPS patch
antennas.
DESCRIPTION
The VJ5101W157GXCMT ceramic chip antenna is a small
form-factor, high-performance, chip-antenna designed for
operation at 1.575 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
• Small outline (10 mm x 3.2 mm x 0.8 mm)
• 50  unbalanced tuning interface
• Linear polarization
• Assembled onto a PCB in the standard reflow process
• Wide transmit / receive range
• High stability in temperature / humidity changes
• Excellent peak / average gain
• Wide operating temperature range (- 40 °C to + 85 °C)
• Material categorization: For definitions of compliance
