BandwidthsModel
TLE35128 series CATV Distribution Amplifiers are broadband outdoor, with GaAs-
Hybrid / Power Doubler technology designed for the cable powered (35-90VAC)
distribution systems where a high quality low noise figure amplifier is necessary
to amplify the signals in both the forward and return paths.
These are all designed with flat operational gain of 35dB in the forward bandwidth
and 20 dB in the reverse bandwidth with a plug-in module. They have an input
variable equalizer and plug-in interstage equalization feature in the forward
bandwidth, a post stage plug-in equalization feature in the reverse bandwidth.
Forward bandwidth features 20 dB variable gain control at the input stage.
Reverse bandwidth features a fixed value attenuator pad at the input stage and a
20dB variable gain control attenuator at the output stage.
These amplifiers are remote powered, 35-90VAC over coaxial network .

Safety
Dimensions

Forward Level Setup:
1. Before applying power to the amplifier make sure that the
input level to the amplifier is not too high, or damage to the
amplifier might occur. To be on the safe side, you should set
the input gain control adjustment to minimum gain (fully
counter clockwise) before powering the amplifier.
2. Set the input equalizer control for minimum slope (fully
clockwise) and install a 0dB plug in equalizer (factory installed)
into the midstage equalizer socket.
3. Now apply power to the amplifier and measure the amplifier
output level at the 20dB output test point. If it is very low then
turn the input gain control clockwise to increase the gain until
the desired output level is reached at the highest operating
frequency. Remember that the level measured at the test point
is 20dB lower than the real signal level at the output port.
4. Turn the input equalizer control to adjust the output level to
be flat across the full bandwidth. The input signal level will now
be flat too. Under this condition there will be best CNR across
the full bandwidth.
5. Now install a plug-in equalizer 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 information.
6. Make a final adjustment of the output slope and output level
with the input gain and slope controls. Always adjust the gain
control, then the slope control in that order.
7. If you are having trouble obtaining the expected output
levels then check the input test point to verify that the levels
are as expected at the input of the amplifier.
8. Record the in/out operating levels and mid equalizer option
used in this station on the lid label, and proceed to the reverse
band level setup.
Reverse Level Setup:
1. If the forward amplifier is not set up, stop and do it now. It is
recommended that the forward amplifier be set up first since its
high gain requires extra precautions be taken before powering.
2. A commercially available reverse sweep and balance test
system is recommended for setting up the TLE35128 reverse
amplifier. With this test system the forward output test point will
be used for a reverse signal injection point, and you should start
your set up at the first amplifier out from the node. Follow the
procedure offered in the test system manual.
3. If you don't have areverse sweep and balance test system
then you will need two people to set up the reverse band, and
they will need to communicate with each other.
4. The procedure is simply explained as follows:
-Reverse signals are all combining to arrive at the node
destination. Therefore the signals should be set up to have
constant levels at each reverse amplifier input.
-Constant input signal levels are achieved by injecting an
XdBmV test signal into the reverse input using the forward
output 20dB test point. Then the reverse amplifier output gain
and slope controls are adjusted to achieve the same XdBmV
input signal level at the following amplifier (or node) input. The
person at the node reports the resulting levels to the person
injecting and adjusting. This gives a unity gain setupfor each
reversespan.
-The person at the node does not have to move to the
adjacent amp each time the setup person moves to the next
amp. This is because the system is being set up for unity gain.
-Remember that the reverse test points and the injection point
are 20dB directional couplers, so your measured levels and
injected levels should be accordingly adjusted.
