Title: Signal isolator
Inventor: ISODA TAKESHI
IPC: H03H7/46
Filed: 2000-08-22
Abstract: PROBLEM TO BE SOLVED: To solve the problems of a conventional signal isolator that two directional couplers are required because one directional coupler has to be connected to each of two filters, respectively, resulting in the increase in the number of components and the increase in the space factor by them on a printed circuit board of a mobile communication unit. SOLUTION: Filters 12, 13 connected with each other via an antenna terminal 11 and a directional coupler 18a connected to the filter 12 form a 1st main line, a directional coupler 18b connected to the filter 13 forms a 2nd main line, and a sub line 19 electromagnetically coupled with the two man lines is connected to a coupling terminal 16 and an isolation terminal 17 to form a directional coupler. Thus, the number of components can be reduced and the space factor of the signal separator on a printed circuit board of a mobile communication device can be decreased.
