Design of a novel lumped element backward directional coupler based on parallel coupled-line theory
In this paper, a novel lumped equivalent circuit for a conventional parallel directional coupler is proposed. The equivalent circuit and design formula for the presented lumped element coupler is derived based on the even and odd-mode properties of a parallel-coupled line. By using the derived desig...

| description | In this paper, a novel lumped equivalent circuit for a conventional parallel directional coupler is proposed. The equivalent circuit and design formula for the presented lumped element coupler is derived based on the even and odd-mode properties of a parallel-coupled line. By using the derived design formula, we have designed the 3 dB and 10 dB lumped element directional couplers at the center frequency of 100 MHz. Furthermore, a chip type directional coupler has been designed to fabricate with multilayer configurations by employing the Low Temperature Cofired Ceramic (LTCC) process. The designed chip-type directional coupler has a 10 dB coupling value at the center frequency of 2 GHz. Excellent agreements between simulations and measurements on the designed directional couplers show the validity of this paper. |
