APAMSJ-147 ISM-Band Surface-Mount Antenna

Abracon's APAMSJ-147 is a dual feeder antenna offering two antennas within one slim compact module. It supports an active GNSS antenna as well as a passive cellular antenna combined in one module. Cable 1 feeds the GNSS antenna, an active dual-band GPS/GLONASS ceramic patch with LNA, providing a high gain, low noise suitable for modern GNSS receivers. The GNSS section offers a high gain LNA of 26 dB ~ 27 dB over a supply voltage of 3 V ~ 5V, and a low noise figure. This matched active module offers easy integration with an excellent VSWR of 1.2:1, and with no additional tuning required.

Cable 2 from the antenna is a passive feed to the penta-band cellular and UMTS antenna. This offers coverage from 825 MHz to 2170 MHz spanning the mobile bands GSM850/900, DCS1800, PCS1900, and WCDMA (Band 1 UMTS). The passive antenna offers peak gain in low band 824 MHz ~ 960 MHz (1.5 dBi) and typical efficiency of 43%, while the high band 1710 MHz ~ 2170MHz (0.5 dBi) and typical efficiency of 32%. The overall antenna module is a compact design being 77 mm Ø x 12 mm high for window mounting in vehicles. It is suitable as an external antenna of tracking devices, and cellular mobile communications.
