Signal distributing circuit
专利汇可以提供Signal distributing circuit专利检索，专利查询，专利分析的服务。并且PURPOSE: To avoid effect on a signal in service by switching momentarily the termination to a signal input and dummy load to a load package being maintenance object and an extension load package at maintenance or extension by means of a switch circuit.
CONSTITUTION: Distribution ports P
1 , P
4 are in service and a distribution port P
2 is under maintenance. In this state, switch circuits S
1 , S
4 are in the operating mode to connect a broad band high frequency signal (main signal) from a signal source E to each load package 3 and the test signal from a test signal input TEST IN to the switch circuit S
2 of the next distribution port P
2 . Further, the switch circuit S
2 is in the maintenance mode to terminate the main signal to a termination resistor (dummy load) R
0 and to input the test signal to the load package 3 being the maintenance object. Thus, the input to the load packages being maintenance object and extension object and the connection of dummy load are changed over momentarily by the switch circuits to avoid the effect on the signal in service.
