Abstract :
In recent days, radio manufacturers are increasingly interested in broadband amplifiers for cellular communication. Demands of customers enforce manufacturers to develop systems compatible for all standards and it is mandatory to accommodate more than one amplifier or tunable amplifier in front end of communication systems. In this paper, design of tunable amplifier is investigated by using Real Frequency Technique and agility of tunable components is provided by digital tunable capacitors.
