A transponder (400) comprising an antenna (401) and an antenna voltage limiter circuit (404) adapted to limit an antenna voltage to a first voltage limit (VPEAK1) when the transponder (400) is in a first operation mode (504) and to a second voltage limit (VPEAK2) when the transponder (400) is in a second operation mode (505), wherein the first operation mode (504) is a mode in which the transponder (400) receives data, and the second operation mode (505) is a mode in which the transponder (400) sends data. |
