On the Integration of Microwave Filters and Waveguide Switches

In this letter, we propose a new device that integrates the functions of a microwave filter and switch (F&S). The key component of the F&S is a modified tuning pin (MTP) that can be used to tune or to detune a cavity or an aperture. In addition to theory, a prototype is also manufactured and tested, showing how the switching function of the new device can be easily controlled remotely.
