General Notes:
1. 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.
NOTES:
1. Tolerance on 3 place decimals
±
.020(.51) except as noted.
2. Dimensions in inches over mm..
