            Abstract : 
We have studied a multi-mode Delay Line Distribution System (DLDS) as the RF power distribution system from klystrons to RF structures for linear colliders. In particular, a 2×2 DLDS has been proposed and studied at KEK for Japan Linear Collider (JLC). It has been proved that the 2×2 DLDS is simple, bus has good transmission efficiency. We have designed RF components of a basic unit of a DLDS using the High Frequency Structure Simulator (HFSS) code. They include the TE01  extractor, the TE11 to TE01 converter, and the TE11 to TE12 converter for TE12 mode. HFSS calculation of the system, which consists of TE01 extractor and TE11 to TE01 converter, shows that the transmission efficiency of each mode is better than 95%. The components, as well as the system are being studied experimentally. A low power test model for the mode stability experiment in 55 m long wave guide in DLDS is also being developed
