This is a resistive power divider to enable frequency coverage from dc to the highest rated frequency. Since resistive power
dividers 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.
