August 2006 [Components] Understanding Mismatch Effects In Power Combining Circuits Power combining theoretically increases an amplifier's effective output power by coherently summing N identical output stages. For example, if one output stage produces 1 W power, coherently combining four stages will effectively increase the output power to 4 W. Practically, the output power will be degraded by the combiner loss and the practical amplitude and phase errors introduced. As the number, N, of channels increases, the difficulty in maintaining minimally ... May 2004 [Systems & Subsystems] Estimate Multiple Carrier Interference Spurious signals created by the presence of multiple carriers in a given bandwidth are a limiting factor in determining a signal channel's dynamic range. These spurious outputs due to system nonlinearities are the result of mixing of fundamental and... |
