Taoglas ASGGB Active GNSS SMD 18mm or 25mm Patches are single-band active GNSS patches covering GPS/GLONASS/BeiDou/Galileo bands. With hidden active circuitry embedded between the ceramic patch and PCB base, the ASGGB patches are designed to allow the user to mount directly onto their device PCB. This eliminates the need for using a cable and connector thus speeding up the assembly process which allows successful soldering of surface mount components to a circuit board via the SMD process. The ASGGB components measure 18mm x 18mm x 6.45mm (ASGGB184.A) or 25mm x 25mm x 6.45mm (ASGGB254.A) and are optimized for a 70mm x 70mm ground plane, however, smaller ground planes can be used.
The ASGGB184.A also includes a two-stage LNA and a front-end SAW filter to reduce out-of-band noise such as from nearby cellular transceivers. This improves the probability of the wireless device passing radiated spurious emissions certifications. As with many high-performance Taoglas patches, the ASGGB series is produced in a TS16949 automotive quality approved facility and each patch is 100% tested for gain (S21) and return loss (S11) to ensure total consistency of performance.
