RF INTEGRATED CIRCUIT WITH TUNABLE COMPONENT AND MEMORY

摘要

An RFIC with memory is described where the memory can be used to house a look-up table for tuning components designed into the RFIC, providing a customized tuning circuit for antenna and transceiver front-end tuning applications. The look-up table can be loaded at wafer level during the manufacturing process to customize an RFIC design for a specific antenna system. The memory can be used to restrict or tailor the tuning range of tunable capacitors and switches within the RFIC to optimize performance in the end application. The resident memory will improve signaling latency when tuning for time critical applications such as channel tuning in a cellular communication system.
