Integrated Power Amplifier (PA) and filter which is part of important component for Radio Frequency (RF) transmitter is designed using Adavance Design Simulation (ADS). The main aims of the design is to provide linear amplifier and filter at the center frequency of 2 GHz and biased at the conditions of class AB. GaAs transistor is used as an active device due to ability in operating at high frequencies...
This paper presents compact structure of bandstop filter with Defected Microstrip Structure (DMS) to produce a triple — band reject response. To prove the concept of the narrow notched DMS, the operating on centre frequency of 4.0 GHz is demonstrated and validated through simulation. The DMS structure is embedded in the middle of transmission lines in order to reject any undesired signals which may...
