Multilayer Microstrip Forms Tunable Bandstop Filters
Tunable bandstop filters are useful for a wide range of applications in eliminating unwanted signals and interference. Designing such filters can be greatly simplified with a new structure fabricated on multilayer microstrip substrates with a metallic diaphragm. This new structure overcomes the limitations of traditional tunable bandstop filter designs and supports simple, low-cost manufacturing processes.1 The new tunable filter...

Sliced Coaxial Cables Form Compact Couplers
Coupled sliced coaxial cables can provide signal coupling in a compact form factor for 50and 75-W systems. With the ready availability of accurate computer-aided-engineering (CAE) tools, it is possible to apply some basic formulas for calculating the dimensions of these structures to achieve a desired amount of coupling on different substrate materials. What follows is a straightforward approach to calculating those dimensions and analyzing coupler designs fabricated with coupled...
