2-10 Overview
MB*/* Installation and Operation Manual
Following the Bode board, a JXP pad facility adjusts the RF level into the interstage hybrid
amplifier and the MDR-*MB/*/II controls flatness and provides equalization. Because these
losses are located interstage, the noise figure is only significantly impacted by the insertion loss
of the forward cable equalizer or broadband cable simulator, and the input pad if its value is
increased from zero.
Following the interstage hybrid is a JXP-*B pad socket (or a splitter and two JXP-*B pad
sockets for dual output) leading into the power-doubling output stage.
Figure 2-12 illustrates the interconnection between these components in the dual-output MB*/*:
