“…In [11], a compact and high-isolation six-channel microstrip diplexer is presented using two pairs of multimode resonators. In [12], a compact tunable microstrip eight-channel multiplexer is investigated using dual-mode stubloaded resonators. In [13], a new quad-channel diplexer operated at 2.45 GHz, 4.2 GHz, 3.5 GHz and 5.2 GHz is proposed, which is composed of folded defected stepped impedance resonators (DSIRs) and feeding lines.…”

In this paper, a six-channel microstrip diplexer is designed and fabricated. It operates at 0.75/0.85/1/1.25/1.6/1.8 GHz for multi-service wireless communication systems. It consists of two stub-loaded resonators, which are integrated by coupled lines. The channels are close together, which makes the proposed diplexer suitable for frequency division duplex (FDD) schemes. The proposed structure has a compact size of 0.025 λg2 where λg is the guided wavelength calculated at 0.75 GHz. The other advantages of the introduced multi-channel diplexer are the low insertion losses of 1.62/1.27/0.43/0.53/1.26 and 1 dB, as well as good return losses of 26/26/25/25/21.7 and 22 dB at 0.75/0.85/1/1.25/1.6/1.8 GHz respectively. A good isolation of less than 22 dB is obtained between the channels. In order to design the presented diplexer a designing technique is used which is based on the proposing of an equivalent approximated LC model and calculating the inductors and capacitors. To confirm the simulation results, the introduced diplexer is fabricated and measured.

“…Traditionally, the dimension parameters of multiplexer circuit is optimized and realized by accumulating resonators one by one according to ideal normalized coupling matrixes. However, this method is suffers from significantly boosted optimization time when the amount of resonators is getting large [14,15]. In the proposed method, each channel BPFs can be synthesized and optimized individually before they are coupled to obtain the sextaplexer, thereby time consuming optimization for multiplexer with large amount of resonators can be relieved.…”

A C-band high-temperature superconducting six-channel multiplexer (sextaplexer) is proposed in this paper. A distributed coupling scheme is introduced, with which the bandpass filter (BPF) in each channel can be designed individually. The computational complexity of the proposed method is linearly increased as the number of the channels is getting larger, which is much lower than the traditional method. The proposed coupling scheme requires no extra matching network, which helps to reduce the size of the multiplexer circuit. The sextaplexer consists of six high-order BPFs with cascaded quadruplet structure. A pair of transmission zeros can be introduced to make the BPF have high selectivity. The example sextaplexer works at the C-band and each fractional bandwidth is about 0.8%. The center frequency ratios and the isolations of each adjacent channel can reach 1.01 and 42 dB, respectively. The measurement results match well with the simulation results, which verifies the effectiveness of the proposed method.
