| 摘要 |
The invention relates to an amplifier module, comprising at least one amplifier (PA), an antenna port (ANT), a transmission port (TX), a reception port (RX), and a circuit arrangement having at least three 90 DEG hybrids (HYB1, HYB2, HBY3), which each divide a respective input signal into two output signals, wherein the two output signals have a relative phase shift of 90 DEG from each other, wherein the antenna port (ANT), the transmission port (TX), and the reception port (RX) are each connected to at least one 90 DEG hybrid (HYB1, HYB2, HBY3). |
