NEW303 A variation of this design sometimes encountered has the coupled line a higher impedance than the main line such as shown in figure 6. This design is advantageous where the coupler is being fed to a detector for power monitoring. The main line response is much wider: for instance a coupler specified as 2-4 GHz might have a main line which could operate at 1-5 GHz. For example, a λ/4 coupled-line coupler will have responses at nλ/4 where n is an odd integer. To achieve greater bandwidths multiple λ/4 coupling sections are used. A single λ/4 coupled section is good for bandwidths of less than an octave.|{3|4|5|6|7|8|9|10|Three|Four|Five|Six|Seven|Eight|Nine|Ten} New Age {Ways|Methods} To Slot Rafii777
