Parallel coupled line
WebSep 1, 2015 · To provide a tight coupling over the wide pass band and avoid from interfering with RF identification (RFID), asymmetrical three parallel-coupled lines (APCLs) have been introduced in our design. A new model for symmetric three parallel coupled lines (SPCL) is presented for a first time. WebMicrostrip filters employing the parallel‐coupled structure are usually of the bandpass or bandstop types. This chapter presents the theory behind coupled microstrip lines. The theory and concepts are applicable to nearly all coupled transmission lines. Two sets of …

WebDue to their physical structure, they can also be called microstrip parallel-coupled line directional couplers. Even and Odd Modes in Microstrip Directional Couplers. According to the current flow in the coupled lines, there are two modes of propagation in quasi-TEM modes—odd and even modes, with characteristic impedances Z0o and Z0e ... WebApr 2, 2007 · Parallel coupled lines are applied to design a microstrip ring hybrid for size reduction and harmonic suppression. A properly combined parallel coupled line with an open stub shows a low pass filter characteristic and equivalently lambda/4 electrical length. By substituting the coupled line for each one of the six lambda/4 parts in the …

WebJun 6, 2005 · Since the parallel coupled-line filter consists of cascade combinations of parallel coupled-lines, the approach mentioned above can be further developed into a miniaturized filter. It is clear that the miniaturized filter based on the combination of the equivalent parallel coupled-lines requires roughly 6(N+1) capacitors for an Nth-order filter WebIn this paper, a compact parallel coupled microstrip band-pass filter (BPF) is used to design a wideband third order of the Tschebyshev elements for an unlicensed WiMAX technology. Some techniques based on the parametrical study are proposed to obtain the desired 10 % operating bandwidth filter response.
WebJun 12, 2009 · Conventional realizations of varactor-loaded tunable filters exhibit high losses due to the degradation of Q factor caused by varactor's losses. These filters also suffer from nonlinear-related problems such as intermodulation distortion due to varactor nonlinearity. In this paper, a new class of parallel-coupled SDL reconfigurable filter is shown. …
