A multi-bit time-delay adjuster with Radio Frequency (RF) MicroElectroMechanical (MEM) switches may be used in MultiCarrier Power Amplifiers (MCPAs) with a feed-forward linearization technique. The multi-bit time-delay adjuster makes it possible to automatically control a time-delay match with very high precision typically required in feed-forward MCPAs. A searching process for the automatic control of time-delay match is also introduced. |
