Hello, I am looking to make my external antenna circuit for “UBLOX MAX - M10” module , i got all electornic component for the antenna circuit as you see in the image , i am just confused to choose a suitable RF antenna for my circuit so how can i choose a suitable antenna for my circuit and or if anyone has a recommendation for a suitable one for my circuit and “UBLOX MAX - M10” module.
Haven’t you asked this already several times here, could you have perhaps continued one of those posts?
Here you want an active antenna, say like the ANN-MB which would work via the 2.5 to 3.3 V DC Bias on the RF Feed.
The circuit gates the voltage output by VCC_RF using the LNA_ENA pin
so ANN-MB represents the antenna schematics shape in the image only? or it has it circuits on the chip?
There are additional circuits in the antenna. The image doesn’t know what antenna you will be using so those circuits are not pictured.
