Abstract:
A power amplifier architecture and front end circuits utilizing the same that connect a transceiver to an antenna are disclosed. The transceiver is configured for a specific operating frequency. An input matching segment is connected to an input port, and an output matching segment is connected to an output port. An amplifier segment includes at least one transistor with a first terminal connected to the input matching segment, a second terminal connected to the output matching segment, and a third terminal connected to a filter with a range of rejection frequencies. The filter is connected in close proximity to a first inductive interconnection tying a junction connected to the third terminal to a ground. A compensator is also connected to the input matching segment and the output matching segment to minimize instability of the filter.
