Abstract

PURPOSE:To eliminate the need for phase matching by connecting a diode to the intermediate output terminal of a circulator and applying a bias voltage to this diode. CONSTITUTION:An RF input signal 20 inputted to the terminal A of the circulator 4 is outputted to the intermediate output terminal C. When a -E(V) is connected to a bias terminal 10, the diode 5 turns off, and the signal at the terminal C is reflected by the diode 5 to return the circulator 4, and outputted from an output terminal B. Then when a +E(V) is connected to the bias terminal 10, the diode 5 turns on, so the signal at the intermediate output terminal C arrives at a grounding point through the diode 5 and is reflected there to reach the intermediate output terminal C of the circulator 4 through the diode 5 again, so that the signal is outputted from an output terminal B. For the purpose, the diode 5 is turned on to change a signal path by 2l, thus making phase shift.

It comes out with a power of ().Here, -E (
When V) is connected, -E (V) is applied to the diode 2 through the choke coil 3, and since it is in the OFF state, it is outputted to the terminal C and as the RF output signal 30.
