Abstract
An adjustable blueprint of microwave quasi-reflection-less band pass filter is presented in this article in order to execute multiple filter responses with the same design. A three-channel quasi-reflection-less filter is considered and a combination between different bands is achieved by combining channels together while maintaining a quasi-reflection-less particularity. The addition of RF switches with variable states insure the overall resilience of the final design by insuring tunable bands and answer the rising need of complex specifications without incrementing the congestion. The complexity of this design can be pushed further by increasing the number and order of the filters along with the quantity of RF switch and accordingly retrieve a higher number of possible configurations.
