Abstract:
The present disclosure relates to a hybrid transformer duplexer apparatus. The hybrid transformer duplexer apparatus includes an autotransformer having a first port, a second port and a tap coupled to a first antenna port. A step-down transformer has a primary winding with a first terminal coupled to the first port of the autotransformer and a second terminal coupled to the second port of the autotransformer, and a secondary winding having a third terminal coupled to a second antenna port and a fourth terminal coupled to a common node.
