The design version for the active microstrip bandpassing filters

The algorithm of the construction of the active microstrip bandpass filter with the application of the corrective element of its frequency characteristic is represented. The corrective element converts initial (the Tchebyshev frequency characteristic of a filter) to the elliptical form near the passband. The microwave linear amplifier compensates the insertion losses. This position is confirmed on the example of the 8-pole L -band filter with bandpass about 8%.
