• GPS L1 band
DESCRIPTION
Operating temperature: - 40 °C to + 85 °C
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.
Frequency range (transmission / reception): 1575 MHz
± 50 MHz
• Transmission / reception at 1.575 GHz
ELECTRICAL SPECIFICATIONS
Note
• Electrical characteristics at + 25 °C unless otherwise specified. 
