The PDM-81M-G series eight- way Power Divider/Combiners covers the band from 2 to 18 GHz in four standard models with and other special models for specific, optional frequency ranges. Each unit uses a multi-section stripline Wilkinson design providing high isolation and low VSWR. 2. For applications below 2 GHz, Merrimac offers a complete line of lumped element power dividers found elsewhere in this catalog. 3. Many models are available from catalog stock for fast delivery.
