Abstract
An electronic device includes multiple antennas to transmit one or more signals, and a transceiver electrically coupled to the antennas. A transmitter of the transceiver may include splitter circuitry with reduced circuit area that may receive an input signal and generates multiple signals. Moreover, a receiver of the transceiver may include combiner circuitry with reduced circuit area that may receive multiple input signal and generates one output signal. The splitter and/or combiner may include combined circuitry including one or more inductors and resistors to provide a desired total impedance. Moreover, in different embodiments, the splitter and/or combiner may have different number of input or output ports.
