Yayın A tunable inductance topology to realize frequency tunable matching networks and amplifiers(IEEE, 2013) Atilla, Doğu Çağdaş; Aydın, Çağatay; Köprü, Ramazan; Nesimoğlu, Tayfun; Yarman, Bekir Sıddık BinboğaCoverage of commercial communication standards such as GSM, UMTS, Wi-Fi and Wi-Max within a single transceiver chip is one of the most desired properties by wireless communication manufacturers. In this regard, communication companies are keenly interested in the design of high power amplifiers for broadband cellular communications to achieve this coverage. In this work, design of broadband tunable matching networks is investigated using Real Frequency Techniques. In practical applications, tunability is needed to compensate for the load impedance variations with environmental effects. In order to be able to work on sample structures, impedance transforming filters with proper topology are chosen and a broadband tunable matching network with a tunability strategy is developed. Eventually a broadband amplifier has been designed using the tunable inductor concept.Yayın A frequency tunable broadband amplifier utilizing tunable capacitors and inductors(2013) Nesimoğlu, Tayfun; Aydın, Çağatay; Atilla, Doğu Çağdaş; Yarman, Bekir Sıddık BinboğaSoftware Defined Radio (SDR) technology aims employing commercial communication standards within a single transceiver unit. Therefore, the design of broadband frequency tunable microwave components; particularly tunable amplifiers have gained considerable importance in recent years. In this work, a tunable inductor topology is proposed, theoretically analyzed and simulated. By using tunable capacitors, tunable inductors were obtained and broadband tunable matching networks are designed. Eventually a frequency tunable broadband amplifier covering 800-7500 MHz band has been realized.
