Cisco GainMaker Low Gain Dual System Amplifier 1 GHz with 42 54 MHz Split Splitters, Directional Couplers, Power Inserter Data Sheet

RF Electronics
GainMaker® Line Extender
1 GHz with 42/54 MHz Split
Description
The GainMaker® Broadband Amplifier Platform includes a variety of
RF amplifiers that address the divergent needs of today’s broadband
networks. All GainMaker amplifiers provide superior 2-way
performance and reliability combined with a user-friendly layout. All
share common plug-in accessories and perform to 1 GHz in the
forward path. The Line Extenders in this family provide a single
forward RF output port while the System Amplifiers provide multiple
forward RF output ports.
The GainMaker Line Extender modules have increased gain and are
mechanically compatible with previous Line Extender II and III
housing bases, often enabling upgrade to higher bandwidth with no
re-spacing or re-splicing. The DC power supply is modular and
located in an updated housing lid for easy access. All GainMaker
Line Extender modules are factory configured with reverse amplifier,
diplex filters, forward interstage pads and interstage equalizer, to
ensure optimal performance. For output level control over
temperature, optional configurations additionally include either
single-pilot Automatic Gain Control (AGC) or a Thermal compensation circuit.
The GainMaker Line Extender has a single forward RF output port and is ideally suited for providing high (bridger)
level RF in the feeder network.

Data is based on stations configured for 2-way operation. AC currents specified are based on measurements made with typical CATV type
ferro-resonant AC power supply (quasi-square wave), and standard GainMaker Line Extender power supply (12/24 V DC, pn 593020).
DC supply has a user configurable 30 V, 40 V, or 50 V AC under voltage lockout circuit. Default setting is 30 V. 40 V or 50 V AC under voltage
lockout may be selected by changing the position of the lockout jumper.
Notes:
1. Reference output tilt is specified as “LINEAR” tilt (as opposed to “cable” tilt).
2. Forward Gain and Noise Figure measured with 0 dB input EQ and 1 dB input pad.
3. Down tilt, the effect of cable, is represented by a (-). Up tilt, the effect of equalization, is represented by a (+).
4. 78 CW NTSC channels loaded from 55 to 550 MHz. Digital refers to 550-1002 MHz loading with QAM carriers at -6 dB levels relative to
analog video carrier levels.
5. X-mod (@ 15.75 kHz) specified using 100% synchronous modulation and frequency selective measurement device.
6. Reverse Gain and Noise Figure for station with 0 dB reverse input pad, 0 dB reverse output EQ, and 1 dB output pad.
7. Reverse Operational Gain, Noise Figure, and Return Loss are specified without reverse switch option. If switch is installed, reduce
Gain by 0.5 dB, increase Noise Figure by 0.5 dB, and decrease Return Loss by 1 dB.
8. 94 CW NTSC channels loaded from 55 to 650 MHz. Digital refers to 650-1002 MHz loading with QAM carriers at -6 dB levels relative
to analog video carrier levels.
9. Distortion performance at reference output levels and tilt.
