Is it normal that 4th pin (ANT-IN) and 5th pin (GND) of M20050-PS-1 are shorted?
Hi.

I have a question about the ANT-IN and GND pins of the M20050-PS-1.

We are currently producing PCBs and mounting components. By the way, the ANT-IN pin and GND are shorted. I checked with the multimeter for unplugged parts, but pin 4 (ANT-IN) and pin 5 (GND) are also shorted. Is this normal?

Hi,

This is normal, pin 4 (ANT_IN) is the connection to the internal antenna. This antenna uses a capacitive feed that requires a GND connection internal to the module to operate.
