Abstract :
The design of narrowband active bandpass filters with high gain and low noise figure is described. The filter configuration is a combination of low-loss suspended stripline resonators and active microstrip circuits with FET devices. Measured results of this filter configuration with two resonators and one active circuit are presented.<>
