Patent attributes
The present invention is a tunable multi-element network for providing impedance transformation. The network may include a first switched capacitor power load modulator circuit and a second switched capacitor power load modulator circuit. The network may further include a series inductive component configured for connecting to at least one of the first power load modulator circuit and the second power load modulator circuit. The network may be further configured for connection to a transmit antenna and a power amplifier. The network may be further configured for receiving an arbitrary impedance from the antenna. The network may be further configured for synthesizing an arbitrary capacitive reactance based on a dynamically controllable phase angle between a switch drive signal provided by the network and an incident Radio Frequency (RF) signal. The network may be further configured for matching the antenna impedance to the power amplifier via the arbitrary capacitive reactance.
