- overview and introduction to the basic concepts of RF combiners and RF splitters.

RF combiners, splitters, couplers and hybrids are a group of circuits and components that are used in many RF applications to split, combine or sample RF power in circuits. Being similar in nature, they are often linked together in explanations or within similar areas within manufacturers catalogues.

2007年，蘋果公司第一台iPhone面試。同年，第四代Wi-Fi無線技術——802.11n——應運而生。在當時剛剛起步兩年的YouTube上大家見到的還是中等解析度視頻，這項無線技術剛好可以滿足針對這一類視頻的消費需求。
