The Taoglas ASGPDF254.A is a single band active GNSS patch covering GPS/GLONASS/BeiDou/Galileo. The ASGPDF254.A has been designed with a dual pin patch to enhance performance by improving multipath rejection so signals can be received and sent more clearly.
With hidden active circuitry embedded between the ceramic patch and PCB base, it has been designed to allow the user to mount it directly onto their device PCB. This eliminates the need for using a cable and connector thus speeding up the assembly process by allowing successfully solder surface mount components to a circuit board via the SMD process. The ASGPDF254.A measures 25 x 25 x 6.5mm and is optimized for a ground plane size of 70*70mm being required for operation however smaller ground
planes can be used.
The ASGPDF254.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 and this improves the probability of the wireless device passing radiated spurious emissions certification.
