Abstract: An optoelectronic transceiver comprises an active linear TOSA circuit mounted on a header. The active linear TOSA circuit includes input nodes for receiving a differential signal pair, a first bipolar transistor, a second bipolar transistor and an electro-optical transducer. A base terminal of the first bipolar transistor is coupled to the two input nodes and an emitter terminal of the first bipolar transistor is coupled to a base terminal of the second bipolar transistor. A collector terminal of the first bipolar transistor is coupled to a first terminal of the electro-optical transducer, the first terminal of the electro-optical transducer also being configured to be coupled to a voltage source. A collector terminal of the second bipolar transistor is coupled to a second terminal of the electro-optical transducer and an emitter terminal of the second bipolar transistor is coupled to a signal ground which is not the header ground.

Abstract: An active linear amplifier circuit mounted in an optoelectronic package includes input nodes for receiving a differential signal pair, a first bipolar transistor, a second bipolar transistor, an electro-optical transducer and a decoupling circuit. A base terminal of the first bipolar transistor is coupled to the two input nodes and an emitter terminal of the first bipolar transistor is coupled to a base terminal of the second bipolar transistor. A collector terminal of the first bipolar transistor is coupled to a first terminal of the electro-optical transducer, the first terminal of the electro-optical transducer also being configured to be coupled to a voltage source. A collector terminal of the second bipolar transistor is coupled to a second terminal of the electro-optical transducer and an emitter terminal of the second bipolar transistor is coupled to a signal ground which is not the header ground.
