The PDM-21(M) series of 2-way In-Phase Power Dividers/Combiners covers 500 MHz to 18 GHz in octave bands. Each uses a conventional Wilkinson design which provides high isolation and low VSWR. 2. Etched PTFE fiberglass stripline circuits are encased in a miniature machined housing that minimizes moding and provides an effective RF shield. 3. These units are generally available from catalog stock for fast delivery. 10/22/08 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531
