general notes: 1. the ctm series directional couplers are miniature three port devices utilizing stripline technolo gy in a connectorized package. each is a multi-section quarter wave coupler designed to cover a broad bandwidth. they are ideally s uited to monitor forward or reflected power with minimal perturbation to the main line signal, signal sampling, control loops and test signal injection devices in bite. 2. a variety of models may be custom ordered with coupling values up to 30 db and covering frequency bands up to 18 ghz. 3. these units comply with mil-c-15370 and may be supplied screened for compliance with additional s pecifications you designate for military and space applications requiring the highest reliability. ctm-m-g series directional couplers 500 mhz to 18 ghz / multi-octave bandwidths / 6, 10 & 20 db coupling / 50 w / stripline / sma for further information contact merrimac / 41 fairfield pl., west caldwell, nj, 07006 / 973-575-1300 / fax 973-575-0531 16aug99 notes: 1. tolerance on 3 place decimals .020(.51) except as noted. 2. dimensions in inches over millimeters. 3. weights are nominal on all outlines. package outline
