CATV Amplier
1218 MHz | DOCSIS 3.1

FX4132R Series type amplifiers with active return are broadband indoor GaAs E-pHEMT Push Pull
distribution amplifiers designed for 1.2 GHz DOCSIS 3.1 supported RF distribution systems such as
those in Cable Television Apartments, Hotels, Hospitals and other applications where a high quality low
noise figure amplifier is necessary to amplify the signals in both the forward and return paths.
Universal JXP style pads applicable for both attenuator and equalizer functions.

INSTALLATION GUIDELINES
This reminder is provided to call the CATV System Installer’s aenon to Arcle 820-40 of
the NEC that provides guidelines for proper grounding and,
in parcular, species that the cable ground shall be con-
nected to the grounding system of the building, as close to
the point of cable entry as praccal.
• Plug in Gain & Cable Slope Controls are reachable under
the Cover. Refer to layout scheme above the RF circuit
for adjustable controls.
• This product is shipped with default 0 dB pads for plug in
gain control and equalizaon.
• Connect only to power adapter supplied with the ampli-
er.
NOTE: All gain and equalizer adjustments are achieved by universal plug-in JXP pads. The
amplier actually uses standard JXP series pads in place of equalizers as well. This is due to
a unique circuit in the amplier that eecvely turns the pad into an equalizer. For instance
if you were to install a 8 dB (or any value) pad in the equalizer socket it becomes a 8 dB (or
same as pad value) equalizer ,aenuang the low frequency by 8 dB while only aenuang
the high frequency by about 1 dB.
FORWARD OUTPUT LEVEL SETUP PROCEDURE
 Before applying power to the amplier, make sure that the input level to the amplier
is not too high otherwise a damage to the amplier might occur. To be on the safe si-
de, you should set the input gain control adjustment to minimum gain (insert highest
pad on input ATT socket) before powering the FX.
2. Set the input and interstage equalizer controls for minimum slope, install a 0 dB JXP
pads at the input and interstage plug in equalizer sockets (factory installed).

3. Now apply power to the amplier and measure the amplier output level at the - 20
dB output test point. If it is low, then place appropriate pad into the input ATT socket
to increase the gain the desired output level at the hig
hest operang frequency. Remember that the level
measured at the test point is 20 dB lower than the real
signal level.
4. Place an appropriate plug-in JXP Pad module into the
input equalizer socket to ensure at signal level across
the full bandwidth. The input signal level will now be f
lat too. Under this condion there will be best CNR
across the full bandwidth.
5. Now install a plug-in JXP Pad module into the midstage
equalizer socket to get as close as possible to the desired output signal slope. The
desired output slope is determined by your system design. Consult your system
planner or your system maps for this informaon. JXP style aenuators are available in
2 dB steps from 0 to 18 dB.
6. Make a nal adjustment of the output level with the input gain control. Always adjust
the gain control, then the slope control in that order.
7. Remember to replace the cover aer adjusng.
