Abstract

This paper proposed a reliable microwave backbone link design from Ujung Batu to Pasir Pengarayan by taking into account the antenna height and the distance. Pathloss 4.0 is used for designing microwave link and link budget analysis. A repeater is added between Ujung Batu to Pasir Pengarayan in order to improve the performance. This is due to an existing highland in between that affect to the antenna height. Mini link 7HC 128 QAM and Andrew antenna P8-6812 are used as microwave equipments. Design microwave links Ujung Batu- repeater and microwave link repeater – Pasir Pengarayan have availability 99.996%. Space diversity technique id used to improve the system as recommended by ITU-R G 826 of 99.999% availability.Keywords : Link budget, Space diversity, Availability, Pathloss 4.0

Abstract

Bandpass filters for millimeter-wave band applications are typically designed using resonators. However, the design of a multilayer coplanar waveguide (CPW) monolithic microwave integrated circuit (MMIC) bandpass filter for 5G millimeter-wave band, n257 with operating frequencies from 26.5 to 29.5 GHz is still not available. Therefore, in this work, a compact bandpass filter for 5G millimeter-wave application was designed with multilayer CPW MMIC bandpass filter based on a meander resonator. The meander resonator of the bandpass filter was designed using low-loss multilayer CPW lines. In designing the bandpass filter, the resonator length and perturbation was utilized to optimize the resonance and bandwidth, and meander resonator was used to miniaturize the bandpass filter. As result, a compact bandpass filter with size of 0.75×0.75 mm2 for 5G millimeter-wave band n257 was achieved. It has bandwidth of 3 GHz, an insertion loss of -2.87 dB and a return loss of -11.1 dB at frequency 28 GHz.
