PORTIERA 35 This page is intentionally blank 36 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 50W W 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 39 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. These are mounted with a single 3mm screw and if it is not properly fastened it may be detached from the PCB by a movement of the connector once it has already been soldered to the path. 40 Component layout SCH0192AR0 41 42 COMPONENT LIST SCH0192AR0 REF.

All of that is performed by a modern and powerful 16 bit micro-controller, which is the main part of the board. Figure 1 shows the block diagram. Figure 1: Simplified block diagram of the control and display board 46 It can be seen that the micro-controller is the heart of the control system, to which the various peripherals (power supply, serial ports, telemeasure socket, AGC port, RF amplifier module, ROM, clock, display and keys) are interfaced. - Power Supply The board is powered with a continuous +24V voltage applied on the J14 connector. From that the +5V voltage, powering the most of the chips (micro-controller, operational amplifiers, display, etc.) is derived by means of a switching converter (see IC19). A +12Vdc voltage is obtained from it as well, by means of a linear conversion provided by the integrated circuit IC8. From this, a -12Vdc voltage is obtained by means of the integrated circuit IC5. The -12V voltage is used to adjust the contrast of the display. - Connectors On the board SCH0223AR1 there are several connectors used as interfaces for the peripherals of the apparatus and the ports for external communication. POWER SUPPLY The connectors J1, J6, J8 e J12 are used to connect the power supply powering the RF modules. The number of power supply used changes depending on the amplifier, up to eight power supply. They are connected in the order shown in Table 1 below. Remaining connectors, if any, are left unconnected. CONNECTOR POWER SUPPLY N° J1 1-2 J6 3-4 J8 5-6 J12 7-8 Table 1: Interface connectors for the power supply Through this connection, each power supply provides the level of voltage and current acquired by the microcontroller by means of an internal ADC. Besides the connectors allow the control board to turn on or off the individual power supply (for instance when an alarm occurs). 47 RF AMPLIFICATION The J3 connector interfaces the control board with the RF amplification section. Through this connector the micro-controller acquires the forward and reflected powers, unbalancing (if any), and temperature of the critic amplification area. It also allows to inhibit the transistors in case of reflected power alarm, by means of a totally hardware, thus extremely fast protection. Depending on the apparatus, this connector may also allow to enable or disable the cooling fans of the critic area. RS485 The J11 connector (10 pin socket) is directly wired to a DB9 female connector placed on the rear panel of the apparatus. This communication bus allows to connect the amplifier to the control (Amplifier Control) module of a high-power transmitter composed by several individual amplifiers. In this case, each amplifier and the Amplifier Control are connected to the same 4-wires RS485 bus and each of them has a unique address (which can be set by means of the keys and the display) for correct communication. In case of single (stand-alone) amplifier, the RS485 connector can be used to interface to the Remote Control Unit (RCU) made by Elettronika S.r.l. This unit allows to monitor and control the remote transmitter from any site provided with PSTN or GSM1 phone connection. Table 2 shows the wiring between the J11 connector on the board and the DB9 female connector on the rear panel, along with the description of the lines. PIN N° ON DB9 PIN N° ON J11 DESCRIPTION Not used Rx- Rx+ +5V GND Not used Tx- Tx+ Not used Table 2: Description of the RS485 connector For more details about the control system contact the distributor or the manufacturer. 48 TELEMEASURES The J9 telemeasure connector (10 pins socket) is directly wired on a DB9 female connector placed on the rear panel. There are input and output digital lines (TTL level) and analog output lines on this connector, which are used to monitor and control the amplifier by means of a general-purpose remote control system. The correspondence between the pins of the J9 connector on the board and the DB9 female connector on the rear panel, as well as the meaning of the various lines, is shown in table 3 below (the directions are in respect to the micro-controller on the board). PIN N° ON DB9 PIN N° ON J9 TYPE DIRECTION Analog Output Forward power (*) Analog Output Reflected power (*) Analog Output Temperature Digital Input 6-7 2-4 Digital Output Digital Input Turning-on control (normally high, active when low) Digital Input Turning-off control (normally high, active when low) DESCRIPTION Interlock: 0V = Interlock Alarm 5V = Normal Ground Free Contact (closed when amplifier is in alarm) (*) You can select by means of two jumpers on the board (JP1 and JP2) RMS or peak power. If there are two jumpers on pins 1 and 2 of JP1 and JP2 connectors, RMS power is selected. Otherwise, if there are two jumpers on pins 2 and 3 of the same connectors, peak power is selected. Table 3: Description of the telemeasures connector The input stage of the digital pins has an internal pull-up towards the 5V power supply voltage. To use these lines it only takes setting a switch to close to earth. When closed, the relevant control (turning on or off) is enabled and the switch may be open again (impulse controls). The interlock pin may be used as protection so that the amplifier is switched off when the digital input level is low. It is possible to use several serially connected switches to make an interlock chain. Usually all switches are closed and the interlock level is low, thus the amplifier is on. If even only one of the switches is open, the 49 level of the interlock signal becomes high (this line has a pull-up towards the +5V power supply voltage as well) and the interlock protection activates switching off the amplifier. Note that in case the interlock protection is not used, the pin 4 of the DB9 telemeasure connector and the earth pin (pin 5) must be short circuited. Otherwise it is possible to disable the monitoring of the interlock chain from menu (see user manual). Figure 2 shows a typical usage for the digital input signals to turn on and off the amplifier and for the interlock alarm. Figure 2: Usage of the digital input signals of the telemeasures connector AGC / EXCITER The connector called J10, as the telemeasures connector and the RS485 bus, is wired to a DB9 female connector placed on the rear panel of the amplifier. This connector allow the implementation of an automatic gain control between an exciter and the amplifier. A voltage signal related to the forward output power supplied by the amplifier is provided through two pins of the AGC connector. Connecting one of these to the relevant input pin of the exciter, this can pursuit a given voltage level, so that the output power is always constant. In order to avoid that, in case of an alarm decreasing the forward power, the exciter increases its output level due to the AGC, thus damaging the amplification stages, the connector is provided with two digital output lines called AGC Alarm. Under alarm conditions, this lines are brought by the micro-controller at a low level, so that the exciter can stop the AGC. Table 4 shows the connection between the J10 connector on the board and the DB9 connector on the rear panel, along with the description of each pin (the direction of the pin is referred to the position of the microcontroller on the board). 50 PIN N° ON DB9 PIN N° ON J10 TYPE DIRECTION Digital Output AGC Alarm 0V = Alarm 5V = Normal Digital Output AGC Alarm 0V = Alarm 5V = Normal Not used Not used Not used Nout used Analog Output Forward power Analog Output Forward power DESCRIPTION Ground Table 4: Description of the AGC connector RS232 The DB9 female connector on the front panel is an external communication RS232 serial port, through which a PC can be connected directly to the amplifier in order to perform operations such as the remote control (by means of an adequate software2) and the update of the microcontroller firmware. The used communication protocol is asynchronous, at a 19200bps speed, 1 start bit, 8 data bits, 1 stop bit, no parity. No hardware flow control is used. The connector is DCE type and the pin used are shown in Table 5. PIN N° ON DB9 DESCRIPTION TxD RxD GND Table 5: Description of the RS232 connector MISCELLANEOUS The J2 (called AUX), J4, J5 and J17 connectors are not used and are there only for future updates. The SW1 dip-switches are partially used for the configuration of the correct mode for the micro-controller. The other switches are not used. It is important that the position of the dip-switches is left unchanged, because changing it may set a wrong mode for the micro-controller, affecting the work of the whole amplifier. For more information about this application contact the distributor of the manufacturer. 51 FIRMWARE UPDATE The microcontroller is provided with a built-in Flash memory containing the firmware. The firmware can be updated with a later version without removing the apparatus from the rack and/or replacing the chip. To upgrade it, connect a PC to the RS232 socket on the front panel of the apparatus by means of a cable DB9 male - DB9 female (pin-to-pin). Launch on the PC the EKAFlash application, select the serial port in use on the PC, choose the update file by pressing the ... key and click on Download button. Eventually, turn off the amplifier from the main switch and then turn it on again. The upgrade of the firmware begins on the EKAFlash window. Fifure 3 shows this window while a firmware is being updated.

CL3NL15 is made up by a band-pass section with 3 resonators and two notch resonators. It may be adjusted on all channels of the YHF TV band (470 - 860MHz) and for any world standard (intercarrier 4.5 - 6.5MHz). The band-pass section is made up by the group of the three resonators, while the two separated resonators are the notches. The filter is symmetrical, as such any notch, upper or lower, can be chosen without any difference. The band width is adjusted by changing the insertion of the two post screws which are between the band-pass resonators; when they are inserted, the band width is increased. To make this adjustment the bolt of each post screw has to be loosened by means of a tubular wrench n° 19. The input and output couplings, which can be reached after removing the protection cups, can be adjusted trough the coupling stubs put in correspondence to the connectors. The adjustment is made by means of a flat wrench n° 8, taking into consideration that the maximum coupling is obtained when the flat sides are parallel to the longer side of the filter, the minimum one when they are orthogonal. Finally, the symmetry of the response is given by the extrusion of the coupling stubs; these are set by loosening the relevant clamps by means of a tubular wrench n° 16. Once these clamps are fastened, they also determine the friction for the rotation of the couplings. The suggested calibration procedure is; 1. Set the measurement instrument on - C.F. = (P.V. + P.A.)/2 - SPAN = INTERCARRIER * 5 (Es. 27,5MHz std. B/G) - RESPONSE = 5dB/div. - ADAPTATION = 10dB/div. 2. Set the coupling stubs of the couplers and the post screws according to the following extrusions, measured from the edge to the body of the filter: C.F. (MHz) COUPLING STUB (mm) POST SCREW (mm) 474 11 21 666 28 20 858 39 16 71 3. Tune the band-pass section on the desired channel and load input and output correctly until an optimal response is obtained. At this stage the tuning of the two notches must be kept distant from each other. Adjust the band width to -27dB at the edges of the screen (es. std. B/G: BW (-27dB) = 27,5MHz). The input and output couplings may affect the tuning of the resonators, as such it takes adjusting them at the same time in little steps. 4. Tune the two notches bringing them to the frequencies P.V.-INTERCARRIER and P.A.+INTERCARRIER. This will cause a variation in response and adaptation of the band-pass. Correct the response by acting on the band-pass tunings. 5. Complete the calibration by acting alternately on the two sides according to this sequence: adjust the coupling, re-tune the notch if it moved and then the band-pass tunings. Repeat these sequence in little steps trying to improve the adaptation. 6. Check the symmetry of the obtained response and if needed correct it as follows: if the lower notch is more marked than the other, insert the coupling stubs, if it is less, extract them. 7. Once the response symmetry is correct, complete the calibration as explained above. 8. It is possible to obtain a particularly favourable response by slightly unbalancing the post screws from the nominal values, so that the post screw on the side of the lower-frequency notch is slightly more inserted than the one on the side of the higher-frequency one. The difference in adjustment should be about 1-2 mm and the best adjustment will be made clear by the appearance of three very marked peaks in the adaptation curve. 9. Once the calibration is completed, reposition the protection cups on the coupling adjustments. PRESCRIPT CALIBRATION VALUE MEASURE 72 VALUE Insertion loss @ V.C.
