Abstract:
An asymmetrical transformer output demultiplexing (ATODEM) circuit is disclosed. The ATODEM circuit of the present disclosure includes N input windings, wherein N is a natural number. Each of the N input windings have input terminals that couple to output terminals of N PAs. The ATODEM further includes M output ports wherein M is a natural number, each of the M output ports having N series coupled windings coupled between a load terminal and a return terminal. The physical attributes of the N input windings, and the N series coupled windings of the M output ports are asymmetrical such that in an Nth operation mode an Nth PA first-load line impedance matches an output impedance of an Nth PA coupled to the input terminals.
