  In Ac­cel­er­a­tor tech­nol­ogy, RF power cou­plers are im­por­tant com­po­nent to cou­ple RF sig­nal to trav­el­ling wave struc­ture. Cir­cu­lar wave­guide TM01 mode is one of the sym­met­ric modes, that is suit­able to use for RF cou­pling. TM01 mode launcher is used as an RF cou­pler in Ac­cel­er­a­tor tech­nol­ogy*. De­sign of a com­pact cir­cu­lar wave­guide TM01 mode-launcher is pre­sented in this paper. The de­sign is based on the prin­ci­ple of mag­netic field cou­pling be­tween a wire loop and TM01 mode of cir­cu­lar wave­guide. The mode launcher ex­hibits high ef­fi­ciency and 3.1% band­width at 3.2 GHz fre­quency with both cir­cu­lar and el­lip­ti­cal loop. Per­for­mance of the mode launcher is ex­per­i­men­tally ver­i­fied and sim­u­lated S-pa­ra­me­ters agree with the mea­sured re­sults. The mode launcher is of com­pact size and is suit­able for ef­fi­cient ex­ci­ta­tion of TM01 mode in cir­cu­lar wave­guide and trav­el­ling wave struc­tures. The launcher is also use­ful for cold test­ing of high power mi­crowave an­ten­nas and Radars.
