Abstract :
An investigation has been presented for the effect of imperfections of NE71000 GaAs MESFET´s on the performance of microwave second-order active band-pass filters. The cascaded technique is used for the design and construction of a fourth-order systems. The frequency responses for both the actual, ideal, and predistortion cases were obtained using computer simulation program (SPICE). The frequency responses are evaluated when the system operates at different conditions of temperature (-50 to 150°C) and radiation (γ-rays up to 80 Mrads)
