Abstract
An apparatus (100) uses power recovery from a combining circuit (125) to improve efficiency. A power combiner (125) generates multiple output signals (127, 133) from a combination of input signals (113, 114). One of the output signals from the power combiner is coupled to a power recovery circuit (135), and energy is recovered and preferably stored for later use.
