Enhanced Balance Bandwidth Quadrature Coupler Using Parallel Coupled Microstrip Lines
A single stage quadrature hybrid coupler with enhanced flat balance over a wide bandwidth is presented in this article. The present coupler is realized by replacing the transmission line sections of the conventional two-branch coupler by their equivalent parallel coupled microstrip lines (PCML). The impedance controlled wide-bandpass response produced by the PCML is utilized to achieve flat bal...
متن کاملDesign and Analysis of Parallel-Coupled Line Bandpass Filter
Abstract A compact microwave parallel coupled line resonator seventh order bandpass filter (BPF) is presented in this paper, consist a 8-parallel coupled line pairs designed for a maximally flat response or Butterworth response at a center frequency of 2.44175 GHz and with a fractional bandwidth, ∆= 0.035. The filter was implemented in a microstrip platform with a permittivity of the substrate ...
متن کاملNovel Rectangular Coupled Line Bandpass Filter
This paper reports a novel band pass filter without any periodic response. The novel filter has been named Rectangular Parallel Coupled Line filter (RPCL) and derived from reforming the conventional parallel coupled line filters. The novel band-pass filter has narrowband response. RPCL filter with center frequency of 475 MHz, 1 dB pass-band of 10MHz and 25 dB stop-band of 50MHz has been reporte...
متن کاملMiniaturization of Multiband Filter using SIR
Filter is very essential component in wireless communication system. Since need of compact devices is increasing day by day, Filter plays very important role in developments of such devices. In this paper, multiband micro strip stepped impedance resonator band pass filters operating in range of 1 to 10 GHz are designed. A series capacitively coupled series micro strip line resonator is modified...
