We briefly review different synthesis techniques for the design of passive microwave components with arbitrary frequency response,
developed by our group during the last decade. We provide the theoretical foundations based on inverse scattering and coupledmode
theory as well as several applications where the devices designed following those techniques have been successfully tested.
The main characteristics of these synthesis methods are as follows. (a) They are direct, because it is not necessary to use lumpedelement
circuit models; just the target frequency response is the starting point. (b)They are exact, as there is neither spurious bands
nor degradation in the frequency response; hence, there is no bandwidth limitation. (c) They are flexible, because they are valid for
any causal, stable, and passive transfer function; only inviolable physical principles must be guaranteed. A myriad of examples has
been presented by our group in many different technologies for very relevant applications such as harmonic control of amplifiers,
directional couplerwith enhanced directivity and coupling, transmission-type dispersive delay lines for phase engineering, compact
design of high-power spurious free low-pass waveguide filters for satellite payloads, pulse shapers for advanced UWB radar and
communications and for novel breast cancer detection systems, transmission-type Nth-order differentiators for tunable pulse
generation, and a robust filter design tool. [--]
