Abstract:
A transceiver selectively operable in a transmission mode and in a reception mode, the transceiver comprising:a transceiver housing; external bidirectional interface lines; housing terminal pins for connection of said transceiver housing with an integrated circuit via said external bidirectional interface lines; first and second multiplex devices; first and second internal lines; a quadrature demodulator switched to said housing terminal pins by said first multiplex device in a reception mode of said transceiver, said first multiplex device being connected to said housing terminal pins via said first internal lines said first internal lines being reception lines including an in-phase line, an inverted in-phase line, a quadrature-phase line and an inverted quadrature-phase line; and a quadrature modulator switched to said housing terminal pins by said second multiplex device in a transmission mode of said transceiver, said second multiplex device being connected to said housing terminal pins via said second internal lines said second internal lines being transmission lines including an in-phase line, an inverted in-phase line, a quadrature-phase line and an inverted quadrature-phase line.
