Abstract:
Methods and systems for power combining in a multi-port distributed antenna are disclosed and may include power combining signals from power amplifiers (PAs) on a chip. The PAs may be coupled to a single distributed antenna via antenna ports. A phase of each of the signals may be matched at the antenna ports via phase-matching circuitry. A characteristic impedance may be configured at the ports based on a location of the ports. The PAs may be impedance matched to the antenna ports via impedance matching elements. A power level of the power-combined signals may be monitored via a power detector coupled to the distributed antenna. The power detector may include an envelope detector, such as a diode. The antenna may be integrated on the chip or may be located external to the chip. The signals may include RF signals and the antenna may include a microstrip antenna.
