Hi,
the job for the FET is to shortend a 13MHz RFID receiver, and open for it
when required.
The RFID receiver must be shortend when the battery is discharged.

Hi,
I need a switch or some kind of FET etc. that has a low impedans (10 Ohm)
when no supply is present.
There is no room for some kind of relay, the housing max hight is 1.1mm
Thanks,
regards Jens

What is the specific application? (Schematics appreciated to a.b.s.e. if
possible).
It's possible an enhancement mode P-channel device with gate pulled low
might do what is required, a depletion mode device, a JFET or even a
diode - depends on what is required.
Cheers
