.1 OPERATING ENVIRONMENT You can install the apparatus in a standard component rack or on a suitable surface such as a bench or desk. In any case, the area should be as clean and well-ventilated as possible. Always allow for at least 2 cm of clearance under the unit for ventilation. If you set the apparatus on a flat surface, install spacers on the bottom cover plate. If you install the apparatus in a rack, provide adequate clearance above and below.
When the apparatus is put within a combined system it is directly connected to the input splitting and output combining systems. Before fully powering the apparatus, check that the output connections of the coaxial cable to the antenna system are working. In order to this it is possible to check the indication of the reflected power at low power levels. Only if the SWR indication on the display is 0, the output power can be slowly increased.
If the jumpers JP1 and JP2 are put in “M” position, the following configuration will be obtained: PIN FUNCTIONS 2 3 4 5 6 7 20 TxD RxD RTS CTS 12V GND 12V In order to use the connector as RS485 socket, the jumper JP3, JP4, JP5 and JP6 have to be positioned towards the serigraphy “RS485”. In this way, the following configuration will be obtained: PIN FUNCTIONS 2 3 4 5 6 7 20 Rx+ RX- TX- TX+ 12V GND 12V 2.
around 32V. Then take the calibration load and connect it between the positive power supply terminal (corresponding to V1) and ground. Turn the trimmer R5 until you read on the display V1 equal to the value measured before with the tester. Then turn the trimmer R33 until you read on the display Idr1 = 3.4A.
To ensure the best reliability for the board operations it is advisable that you turn the unused trimmers (those corresponding to the unused readings connectors) counterclockwise until they reach the zero position (you will hear a click). 2.6 PREVENTIVE MAINTENANCE To ensure maximum performance and minimum repair trouble, we strongly recommend you to follow the below stated headlines for preventive maintenance: 1. check antenna installation and ground connection at regular intervals; 2.

1kW LDMOS POWER MODULE MTF0050AR0 DESCRIPTION The 1000W output power PEP amplifier module has been realized by coupling four 250W Video power modules. A 4-way Wilkinson coupler, completely balanced by means of power resistors, has been used in output. This way an excellent de-coupling between the amplifier is obtained, as well as the possi470M H z bility to work even with only one ac860M H z tive module.

TESTING AND CALIBRATION INSTRUCTIONS The output filter Mod. CL4NL22 is made up by a 4-resonator band-pass section and two “notch” resonators. It can be adjusted on all the channels of the TV UHF band (470 ÷ 860MHz) and on all the world standards (intercarrier 4.5 - 6.5MHz). The pass-band section is made up by the group of the four resonators, while the two separate resonator are the notches. The filter is symmetrical, thus there is no difference between the upper and lower notch.
• Set the coupling stubs and the post screws according to the indicative protrusion from their edge to the body of the filter listed in the table. • Tune the band-pass section on the wanted channel and load input and output correctly to obtain an optimal response. At this stage the tuning of the two notches have to be kept distant from one another. Adjust the band width to -35dB at the limits of the screen (Es. std. B/G: BW (-35dB) = 27,5MHz).
