It is able to supply a power of 250W (peak sync.) in class AB and is completely realized with LDMOS technology. The power supply of the apparatus is given by a switching power supply for the RF power module and a traditional transformer for the control board. The protection board uses all the potential of a microprocessor to check all the parameters of the amplifier module and the voltage of the power supply. An output band-pass filter provides for the attenuation of the spurious products. The final result is a compact apparatus, it is all inside a standard 19”-4U cabinet, with a very good price-to-quality ratio. 14 1.2 TECHNICAL CHARACTERISTICS RF SECTION Frequency range Output power Gain RF Input impedance RF Output impedance I.M.D. (3 Tones: -8, -10, -16dB) RF Spurious products Filter insertion loss RF Input connector RF Output connector 470 - 860MHz 250W 13dB +/-1 50Ω 50Ω < -54dB (with IF Pre-corrector) Better than -60dB < = 0,6dB N Female N Female Power Supply Typical power consumption RS232 Socket Telemeasuring socket Cabinet Dimensions Weight Ambient temperature Humidity 90-260VAC 600VA (Black) DB9 Connector DB9 Connector Rack 19”-4U 421x368x178mm 25kg -5° to +45°C 20% - 90% FWD Power REF Power Temperature IDC VDC 300W 20W 70°C 14A Min 5V - Max 34V GENERAL PROTECTION THR. 15 This page is intentionally blank 16 Section 2 - Installation Contents: 2.1 Operating environment 2.2 Preliminary operations 2.3 Telemeasuring socket connections 2.4 RS232 / RS485 Socket connections 2.5 Control system 2.6 Preventive maintenance - Front panel - Rear panel 17 2.1 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. Do not locate the apparatus directly above a hot piece of equipment. 2.2 PRELIMINARY OPERATIONS Correct installation of the equipment is important for maximum performance and reliability. Antenna and earth connections must be installed with the greatest care. The equipment adjustment isn’t need, because the unit is completely adjusted by our technical staff. This is the installation procedure: 1. connect the power supply cable of the transmitter to the auxiliary socket on the rear panel of the amplifier; 2. connect the power supply cable of the amplifier to the electric network (90-260VAC); 3. connect the exciter / antenna cable to the RF IN and RF OUT on the rear panel of the amplifier. RF IN RF IN WARNING!!! FOR ELECTRICAL SAFETY REASONS AND IN ORDER TO KEEP THE APPARATUS SAFE, THE GROUND TERMINAL OF THE APPARATUS MUST BE CONNECTED TO THE EXISTING GROUNDING SYSTEM AND NOT BY USING THE SHIELD OF THE OUTPUT COAXIAL CABLE. 18 Before powering fully 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. At maximum output power, some watt might be shown as reflected power 2.3 TELEMEASURING SOCKET CONNECTIONS PIN N° SIGNAL TYPE IN / OUT Ground DB9 Socket Analog FUNCTION Output Digital Input Digital Output Digital Input Analog Output Analog Output FWD Power 0 to 5V Floating: ON - GND: OFF Valid only in remote (Pin 6= GND) 0: Alarm - 1: No alarm TTL Level Not used Floating: Local GND: Remote (Pin 3 Command accepted) REF Power 0 to 5V Temperature 0 to 5V Not used 2.4 RS232 / RS485 SOCKET CONNECTIONS The DB9 connector can be used in two modes (RS232 or RS485) depending on the position of the DipSwitch.

The turn-on key allows to turn on and off the transmitter. In case one of the monitored measures is in alarm, the transmitter will show this. If the value of the measure goes back to normal, the control system will turn on the transmitter again. After 5 cycles of turning on and off the transmitter will be kept switched off until the user turns it off. Meaning of the LEDs - LED ON: The LED ON is lit when the turn-on command of the transmitter is inserted. - LED REMOTE: the LED REMOTE is lit when the remote commands have been enabled by the telemeasuring connector or when the transmitter is controlled trough the RS232 port. - LED ALARM: the LED ALARM is lit when the transmitter has been turned off due to a failure. 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. keep your apparatus clean and dry externally: this will ensure continuous functioning of the front panel controls; 3. if the apparatus has not been used for a long period of time combined with exposure to extreme environmental conditions, open the unit and make a visual inspection. Remove salt, water or ice with a moist cloth before turning the apparatus on. Check that the cooling fans are running freely. 4. for general maintenance and top performance, call an authorized service technical to give the apparatus and the complete antenna/earth connection installation a general check each 12-18 months; 5. check at regular intervals that the air intake located on the front panel is free of dust. If there is visible dust, remove it by means of a soft brush. 20 Front panel LCD Display RF Monitor connector Function keys Status LEDs Main switch DESCRIPTION 21 Rear panel DESCRIPTION Power supply socket Auxiliary socket Breaker RS232 Socket Telemeasuring socket RF Output connector RF Input connector GND 22 _______________________________________________________________________________________________ Section 3 - Diagram Contents: - Cable diagram - AUTV/250LD Component layout - RF Section Block Diagram - SCH0192AR0 (250W UHF LDMOS Amplifier module) - SCH0122BR1 (Control board and display) - SCH0128AR1 (Amplifier interface) - E0012 (SP500/27-48 Switching power supply) - 06604A (UHF TV Output Filter IMD Suppressor) 23 24 25 26 200W UHF LDMOS AMPLIFIER MODULE SCH0192AR0 DESCRIPTION The RF module is an integrated TV linear amplifier designed for UHF band, this module employs push-pull LDMOS technology in order to achieve very good efficiency, high linearity and reliability. LDMOS transistors operate in AB class. It is a wideband amplifier over the full frequency, no adjustment is required for the channel change. The board includes RF section amplifier, bias circuit, protection circuit and matching networks. A silver plated copper plate is brazed with PCB in order to obtain low thermal resistance. Providing a minimum of 200W Pk sync linear power, this module is the perfect amplifier for any broadband UHF power transmitter.

Close the input and the output of the module by connecting them to a 50Ω Ω dummy load and connect the spectrum analyser through a directive sample, in order to look for self-oscillation of the module, if any (anyway the module has been designed so that it would not self-oscillate even if totally decoupled, without any input or output load). STEP 2. Check the voltages of the polarisation circuits without assembling the transistors first: connect the 32V power supply to the proper turret by means of a fastening screw, then give power and check data: - the stabilised voltage on the zener diodes DZ1 and DZ2 is about 15V compared to the ground; - the stabilised voltage on the zener diodes DZ3 and DZ4 is about 6.8V compared to the ground; - the voltage on the pads to which the gates of the LDMOS transistors will be soldered (R23 and R24 resistors side) changes from 0V to a maximum value of about 6V when moving the relevant trimmer (R7-R8). STEP 3. Check the work of the protections. - Set both trimmers so that there is a value of about 4.5V on the pads of the gates; - solder some wire to the pad between the two LEDs, next to the serigraphy of the input hybrid H1; Solder a wire - in order to check the work of the protections aboard, a power of about 4V has to be supplied to the wire, for example by touching with it the reophore of C23 or C24 which is not connected to ground; the two red LEDs will immediately light up and the two RF transistors will be switched off at the same time: the polarisation current (2A) will decrease to 0 and of course the gain curve displayed by the spectrum analyser will decrease; - after this it is important to restore the position of the two trimmers for the minimum voltage! Then disconnect the 32V power supply. STEP 4. Fastening of the LDMOS transistors: after properly cleaning the plate surface, smear a thin layer of silicone fat on the lower side of the flange of the MOSFETs, fasten them to the heat sink and solder the gate first, then the drain. Solder the two 13pF (ATC) chip capacitors and above them the two 1-5pF 29 capacitive trimmers, between the two pair of gates, as shown by the mounting plan. STEP 5. Connect serially a c.c. amperometer to the power supply, with scale starting from more than 5A (i.e. 10A). STEP 6. Power the module and check the MOSFET is not absorbing current; this means that the device is integral and working correctly. STEP 7. Slowly turn the R7 trimmer until the MOSFET absorbs 1A, always checking that there are no self-oscillation; under this conditions it is possible to check by means of a digital tester that the voltage on the gate is about 5.2-5.4V. STEP 8. Repeat the previous step for the other section of the module, this time turnign R8 and checking that the indication of the current on the amperometer increases to 2A total (which includes the current of the other device left on). STEP 9. Check the response curve of the module by means of the network analyser. STEP 10. Check the response curve for low signal with centre 660MHz and span 500MHz, 2dB/div. STEP 11. The curve should be similar to the one enclosed, with a tolerance of ± 0.5dB. To obtain this, act on the four trimmers C41-C41a and C42-C42a with the proper “calibrator”, inorder to flatten the curve as much as possible, especially at the edged of the band which represents the minimum values. STEP 12. Finally, check that the current in stand-by does not increase by more than 15÷20%, reaching at worst 2.3÷2.4A when the heat sink is hot and not ventilated. Note: when mounting-removing the PALLET on the heat sink, tightly fasten the screw of each all “N” input and output connectors.

Both the RF and power supply parameters are continuously monitored in order to guarantee optimal performance in every working environment: - amplifier supply voltages - amplifier supply currents - power module working temperature - amplifier forward RF power - amplifier reflected RF power Vdc; Idc; Temperature; FWD Power. REF Power. The board is based on a flash microcontroller working at a frequency of 20MHz, able to read the parameters, control the amplifier and communicate with any PC connected through RS232/RS485 line. Besides, the microcontroller is programmable, thus it is possible to change the internal program by connecting the appropriate programmer to the J3 connector and this to a computer. The boards contains a 16 characters x 2 lines display and two keys to change the parameter currently shown. There are also 3 different LEDs. The green LED indicates when the amplifier module is ON, the red one is lit when an alarm in occur and the yellow one indicates the remote control of the amplifier. OPERATING CONTROL As indicated in the previous section, the boards is able to read in real time all the necessary parameters to control the amplifier. When the operator turns the amplifier on the display shows the software release number. After a few seconds the amplifier is switched on and the first parameter shown on the display is the forward RF power (“FWD Power”). When a value read is out of the allowed boundaries, the microcontroller activates (after five scans to be sure) the corresponding alarm indicating this on the first line of the display, and showing on the second line the physical value. When the alarm is active, the microcontroller switches the amplifier off and restarts the time counter (3 and 6 seconds). The microcontroller internally stores the number of occurred alarms and if it reaches 5 the whole equipment is definitively switched off. In this case, if the operator needs to restart the machine, it is necessary to switch it off and on again (locally o by remote). When the machine is working normally on the first line shows “TV AMPLIFIER UHF” and the second line shows the parameter with the format “parameter = xx.x unit”. The two keys on the frontal panel allow to change the currently shown parameter: the left one goes to the next parameter and the right one goes back (in sequence Vdc, Vac, Temperature, Idc, FWD, REF). If the amplifier is switched off, the “STAND BY” indication is shown on the display and the backlight is turned off. The amplifier can be remotely controlled by serial line (contact ELETTRONIKA for details). It is configurable as RS232 or RS485. 36 Note: When changing the voltage of the device from 230 to 110VAC, it also takes acting on the SW3 switch on the display board. Failure to do this may result in damages to the device. 37 38 39 COMPONENT LIST SCH0122BR1 Part Name/Number Description Qty. Comps.

It is simply composed of one temperature sensor, a voltage regulator, some passive componentes and a 10 pin connector J2. This connector has to be connected to the corresponding one of the SCH0122BR0 board. The LM317HV (IC1) integrated circuit is an adjustable 3-terminal positive voltage regulator used to make more stable the power supply voltage of the amplifiers fan. The LM35DT (IC2) integrated circuit is a precision temperature sensor whose output voltage is proportional to the Celsius (Centigrade) temperature. It does not require any external calibration or trimming. The package is a plastic TO-220 model and the heat sink is directly connected to the amplifier.

It can be regulated on all the channels of UHF TV band (470 - 8690MHz) and according to all world-wide standards (intercarrier 4.5 - 6.5MHz). The bandpass section is composed by the three middle resonators, while the two resonators apart are the notches. The filter is symmetrical, therefore the choice of lowest and highest notch is indifferent. The bandwidth and the notch depth are predetermined, so they don’t need any regulation. The input/output coupling are regulated by means of the two screws which are in position opposed to every connector. The regulation is carried out with a screwdriver, considering that when the screw lines are parallel to the longer side of the filter the coupling is maximum, otherwise if orthogonal it is minimum. The twist friction of the couplings can be set acting on the hexagonal clamps with a no. 12 key. TUNING INSTRUCTIONS The advised sequence is the following: 1. Set the instrument state as follows: - C.F. = (V.C. + S.C.) / 2 - SPAN = INTERCARRIER * 5 (E.G. 27,5MHz std. B/G) - TRANSMISSION SCALE = 5dB/div. - REFLECTION SCALE = 5dB/div. 2. Turn the bandpass section on the required channel, and match input and output until a correct response is achieved. During this step keep the tunings of the two notches well far away from the response. Fit the curve at the center of the screen, so as to get the same attenuation at the borders. The input/output couplings can influence the external resonators, therefore it will be necessary to repeatedly fix the former after the latter in small steps. 3. Tune the two notches to P.V.-INTERCARRIER and P.A.+INTERCARRIER frequencies. This will vary the response and matchning. 4. Adjust the bandpass external tunings. The lower notch side tuning shall be a little unscrewed, whereas the upper notch side tuning will have to screwed. 5. Enhance a little the lower notch side coupling (the coupling screw toward the filter lenghth). Improve the calibration alternatively acting on two sides according to this sequence: regulate the couplings, re-tune 49 notches if it has to be moved and then the bandpass tunings. Execute the sequence in small steps aiming to improve the matching.
