This is a resistive power divider to enable frequency coverage from dc to the highest rated frequency. Since resistive power divider do not
provide a high degree of isolation (basically isolation equals the insertion loss between ports), an amplifier such as Mini-Circuits' ZFL
series is recommended when high isolation is required. Matched power rating 0.75W, internal load dissipation 0.375W.
