We have used your M20057 Active antenna for GPS in a upcoming large scale product. we don't find any help or reference about how to choose the resistance AT1 & inductor L for AT2 . anyway for AT1 we short it with 0 ohm resistance to ground. but for AT2 inductor, its mentioned as TBD, please suggest us a reference value to start with, we use double sided Fr4 PCB 1.6mm and entire PCb size is around 30mmx50mm, with some other LTE & BLE modules.
we need help on this,urgently.Thank you
