The method is based on the real frequency theory. Gain, bandwidth, vswrand group delay are the optimized characteristics. Optimization is done with the J.J. More subroutine which is an improvement of the Levenberg- Marquardt algorithm. These integrated active low- pass and bandpass filters are used in the field of telecommunications area. Applications are given with one or several fet,several equalizers and attenuation poles which are necessary for broadband filters. Theory is favourably extended to distributed domain with transmission lines and stubs. Low- pass and bandpass examples are given up to 14 GHz in localised and distributed domains. Responses of filters can have asymmetric frequency characteristics. A cadprogram has been written and named freelcd.We give the different subroutines and say that freelcdis useful for microwave integrated active filters.
