Beschreibung
Zusammenfassung:	A transceiver interface for a phased array element includes a first magnetic circuit having a primary coil and a secondary coil, a second magnetic circuit having a primary coil, a secondary coil and a tertiary coil, a main amplifier path and an auxiliary amplifier path, the main amplifier path coupled to the primary coil of the second magnetic circuit and configured to receive a quadrature signal, the main amplifier path configured to provide a quadrature output signal, the auxiliary amplifier path coupled to the primary coil of the first magnetic circuit and configured to receive an in-phase signal, the auxiliary amplifier path configured to provide an in-phase output signal, a selectable output circuit configured to selectively combine the in-phase output signal and the quadrature output signal, and a low noise amplifier (LNA) coupled to the tertiary coil of the second magnetic circuit.
