Description

rugged stripline-constructed units that can be used

either to divide or combine R.F. power. A signal

incident at the sum (Σ) port will yield in-phase

amplitude balanced signals at the output ports.

Conversely, a signal applied to the difference (Δ)

phase signals at the output ports.
