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.
