Branch line coupler原理

WebA novel compact branch-line coupler operating in two arbitrary frequencies is proposed, analyzed and designed. Stepped- impedance stubs are used in the branch-line coupler to achieve dual- band applications. Parameters of the structure are chosen and provided for design guidelines. Broader operating frequency ratios and compactness are achievable. … WebSo, let’s take a look at a particular coupler that is able to provide us with a plus or minus 90-degree phase shift and also split our signal into two pieces. It’s called the Branch-Line Coupler and it is shown here. It’s a basic …
