Abstract
An antenna (L) diagnostic device of a resonant circuit associated with an amplifier includes a first transistor (HS1) and a second transistor (LS1) connected and an amplifier output (OUT1). The first transistor (HS1) and the second transistor (LS1) are mounted symmetrically and the amplifier output (OUT1) is located between the two transistors. The device includes: elements for measuring a current flowing in a connection of each of the transistors; first elements for generating an input signal connected to the first transistor; second elements for generating an input signal connected to the second transistor; and electronic elements (8) with an output supplying an output signal representative of the potential (V_OUT1) at the amplifier output. A method for diagnosing an antenna implementing such a device is also described.
