Abstract

A signal divider 1 can be miniaturized in which divided signals do not interfere with each other and, at the same time, DC power does not creep into each other. Since a signal dividing circuit 11 is a lumped constant circuit and each element can be made as a chip element, the signal divider 1 can be miniaturized. A division ratio of divided signal output from a first division output terminal OUT1 and a second division output terminal OUT2 can be set by a circuit A and a circuit B. Since a circuit C is connected in parallel with a series circuit composed of the circuit A and the circuit B to produce resonance at a usage frequency, a sufficient amount of isolation between the first division output terminal OUT1 and the second division output terminal OUT2 can be guaranteed. DC power supplied from the first division output terminal OUT1 and the second division output terminal OUT2 can be prevented from creeping out by the capacitors C2, C4.
