High isolation diplexer using the hybrid coaxial and microstrip resonators for RF/microwave communication systems
High isolation diplexer using the hybrid coaxial and microstrip resonators for RF/microwave communication systems
One of the major passive components, which affected the performance of broadband RF/microwave communication systems, is the diplexers. This paper presents a new approach for designing a high selectivity diplexer, which is based on compact and high unloaded quality factor hybrid coaxial and microstrip resonator bandpass filters (BPFs).
