The BIAS-T/Regulator module is designed to provide a reliable, rugged interface between a plug-in wall transformer (whose output has high ripple under load and poor load regulation) and the sensitive electronics of a typical LNB. The circuit consists of an LC filter network, 3 terminal voltage regulator, microstrip transmission line with DC block and inductive voltage injector. A suitable wall transformer with mating mil-spec connector is available to complete the system.
