Abstract:
1. A hybrid matching system for use with a transmitter and receiver, said hybrid matching system comprising: a pair of transmitter nodes for providing a differential transmitter signal for transmission; a pair of receiver nodes for receiving a differential received signal; a pair of line terminals to interface with a transmission line; a first transformer including a first set of windings coupled to said pair of transmitter nodes, and a second set of winding, said first transformer providing amplification of the differential transmitter signal; and a second transformer including: said impedance network including a first impedance unit coupled to the second set of windings of said first transformer, a second impedance unit coupled to said first impedance unit and to the second set of windings of said second transformer, and a third impedance unit coupled to the second set of windings of said first transformer and the first set of windings of the second transformer, said first and second impedance units also being coupled to a first receiver node of said pair of receiver nodes, and said third impedance unit being coupled to a second receiver node of said pair of receiver nodes.
