Abstract :
The design, fabrication, and measurement of a GaAs monolithic, active bandpass filter with a passband from 4 to 8 GHz is described. The circuit uses a set of cascaded lumped- and distributed-element LC circuits isolated by a feedback amplifier to realize an equivalent fourth-order filter response. The final circuit was fabricated on a 3-mm*2-mm GaAs substrate.<>
