RF Combiners – RF Dividers from Werlatone – What To Consider When Specifying Your Requirement
Isolating Termination Dissipation
Isolating terminations enable the dissipation of power due to various unbalances and possible input failures. In the case of high power RF Combiners – RF Dividers from Werlatone, however, it may be a system layout and/or cost which determine whether to include internal terminations with enough dissipation capability to absorb the unbalanced power that results from one or more input failures.
A schematic representation of four 250 Watt amplifiers feeding a 4-Way RF Combiner, outlines the power output and the power dissipation requirement associated with various input failure scenarios. It should be noted that all losses shown in the chart are independent of the combiner insertion loss.
