TLE35128

Bandwidths Model

TLE35128 series CATV Distribution Amplifiers are broadband outdoor, with GaAsHybrid / Power Doubler technology designed for the cable powered (35-90VAC) distribution systems where a high quality low noise figure ampl ifier is necessary to amplify the signals in both the forward and return paths.

These are all designed with flat operational gain of 35 dB 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 in put 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

All dimensions are in mm(inch)

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 a reverse 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 reverse span.

- 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.
