Abstract
A transceiver device comprising transceiver circuitry (5) coupled to one or more antenna ports (2; 2′) by a balun arrangement (Lb, Lu; Lu′). For each of the antenna ports (2; 2′) an antenna switch (Ta; Ta′) is present having an antenna enabling input (4; 4′) and being arranged to connect an unbalanced coil (Lu; Lu′) from the balun arrangement (Lb, Lu; Lu′) to the antenna port (2; 2′) and a ground port (3). Also an electro-static discharge (ESD) protection circuit is provided with an ESD switch (Te; Te′) arranged to connect the antenna port (2; 2′) to the antenna enabling input (4; 4′) of the antenna switch (Ta; Ta′). The ESD switch (Te; Te′) has an ESD switch control input (A) connected to an ESD trigger arrangement (Rtrigger).
Claims9
A transceiver device comprising transceiver circuitry coupled to at least one antenna port by a balun arrangement, and for each of the at least one antenna port:
- an antenna switch having an antenna enabling input and arranged to connect an unbalanced coil from the balun arrangement to the antenna port and a ground port, and
- an electro-static discharge (ESD) protection circuit,
- the ESD protection circuit comprising an ESD switch arranged to connect the antenna port to the antenna enabling input of the antenna switch,
- the ESD switch having an ESD switch control input connected to an ESD trigger arrangement.
