Coupled resonator diplexer for LTE-advanced system

الملخص EN

This paper presents the design of a microstrip hairpin diplexer.

The design is based on coupled-resonator structure using U-Shaped resonators.

It is designed to meet The Long Term Evolution-Advanced (LTE-A) system Band 7, operating at uplink (UL) : 2.50–2.57 GHz and downlink (DL) : 2.62–2.69 GHz for base transceiver station antenna.

The structure has three ports with 10-coupled resonators with direct coupling to produce diplexer with chebyshev filtering response.

The diplexer does not involve any
