General Notes:
1. 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.
