Introduction

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 6.45mm 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. As with many high performance Taoglas patches, the series is

produced in a TS16949 automotive quality approved facility, and each patch produced is 100% tested for

gain (S21) and return loss (S11) to ensure total consistency of performance.

Typical Applications Include:

-

Wearables

-

Asset Tracking

-

Navigation Systems
