Resumen
This paper uses a simple configuration to implement microwave transversal filters
based on microstrip technology. The structure is of second order and implements two
transmission zeros and two reflection zeros in the frequency response of the filter. The
basic configuration consists of input and output ports coupled in a shunt configuration to
two printed resonators of different lengths. A modification of the original structure is
introduced to allow an additional direct coupling between the source and the load.
Depending on the value and the sign of the coupling terms, different frequency responses
can be obtained. In this way, small modifications in the basic structure allow to obtain
band-pass or band-stop responses. Following this circuit topology, the paper discusses the
possibilities to have transmission zeros in the real or in the complex plane and their effects
on the frequency response and on the group delay of the filter. Also, two practical
implementations in ...
