MODEL 1584-45 RF SPLITTER
1.0 General
1.1 Equipment Description
The Model 1584-45 is four, five way, 0.95 - 2.05 GHz, 0 dB gain splitters in a 1 Rack Unit chassis with
redundant 100-240 ±10% VAC power supplies. Each splitter provides fused DC power insertion on the
input connector center pin, surge protection, and excellent RF characteristics. Each splitter has a monitor
connector on the front panel and four outputs on the back panel. Two individual 100-240 ±10% VAC input
power supplies provide a diode OR’d +24 VDC voltage for internal amplifiers and for DC to power
external amplifiers (often Low Noise Block converters or LNBs) through DC power inserters. Each LNB
power line is separately fused. A surge suppressor on each splitter input protects against high voltage
transients. All splitter outputs are AC coupled so no DC appears on their center conductors. On the front
panel, green LEDs indicate presence of +22 VDC at each LNB power supply output and DC voltage test
points allow monitoring this voltage with a voltmeter. Presence of power from the +24 VDC power
supplies is shown by the AC Power A and B green LEDs.
