| 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° 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° 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° hybrid (HYB1, HYB2, HBY3). |
