Abstract: | A broadband dumb-bell-shaped 45deg phase shifter is presented using a new design comprised of open-circuit and short-circuit multi-section stubs. A wideband phase shifter operating over the frequency range 2-6 GHz was designed and fabricated for verification purposes. It was measured to have a bandwidth of about 100% for a maximum phase deviation of plusmn3.2deg, and maximum insertion loss of 2.1 dB. |
