摘要
A broad band phase shifter of the present invention can be used in a microstrip conductor and includes a power divider disposed along a microstrip conductor. The power divider has first and second outputs. A reference transmission line is disposed on the microstrip conductor and connected to the first output of the power divider. A phase shift filter device is disposed on the microstrip conductor and connected to the second output of the power divider. The phase shift filter device comprises a 180 degree phase shift coupled line structure formed of a first substantially linear 90 degree phase shift parallel line section, and a second substantially linear 90 degree phase shift parallel line section coupled to the first parallel. line section. The first and second 90 degree phase shift parallel line sections have parallel lines that are spaced about five mils apart. The first and second 90 degree phase shift parallel line sections also have parallel lines that are offset to each other.
