Isolator

摘要

The intersection angle ( THETA 1) formed by the central conductor (2) connected to an input port (P1) and the central conductor (3) connected to an output port (P2) is set to more than 120 degrees, preferably about 130 to 150 degrees, for example 140 degrees. The central conductor (4) connected to a terminating port (P3) preferably bisects the above-described intersection angle ( THETA 1) and may be set to either 110 degrees or 70 degrees, for example. The resistance of a terminating resistor (R) connected to the terminating port (P3) is set to about 200 to 500 OMEGA , for example 300 OMEGA . <IMAGE>
