General Notes:
1. The basic power divider is a hybrid junction with one of its ports internally
terminated. For in-phase power division, such as provided in the PDG-02A series,
the E port is internally terminated.
2. Careful design and construction insure phase and amplitude uniformity between
units. Additionally, these units provide excellent transfer phase linearity and
amplitude flatness. These characteristics are of critical importance to the success-
ful design of modern multi-channel receivers, transmitters and antenna systems.
3. Merrimac Power Dividers/Combiners are available in a variety of packages to
suit most requirements. The surface mounted versions in the PDG-02A series use
lumped element design. This approach is particularly appropriate for those appli-
cations where small size is important.
