¶ General Description
The Echo 27 is a miniature embedded ceramic patch antenna designed for GPS L1 (1575.42 MHz) applications where space efficiency is critical.Despite its compact 15 mm footprint, the Echo 27 delivers strong performance with RHCP gain of 24 dBiC, ensuring reliable reception and fast satellite acquisition. The integrated LNA boosts sensitivity while maintaining low noise, providing stable operation even in challenging environments.
Its small size, efficient design, and low power consumption make it ideally suited to portable, low-power, and space-constrained GPS devices.
Supplied as standard with 100mm coax cable and terminated with a U.FL/I-PEX connector. Alternative cable lengths and connector types can be fitted for volume requirements.
