Abstract
An electronic device includes multiple antennas to transmit one or more signals, and a transmitter electrically coupled to the antennas. The transmitter has splitter circuitry that receives an input signal and generates the signals. The splitter circuitry includes a pair of inductive elements that are inductively coupled together. The splitter circuitry includes capacitive elements to absorb parasitic input and output capacitance. In additional or alternative embodiments, the splitter circuitry may be in the form of combiner circuitry and disposed in a receiver of the electronic device.
