Exciter/Transmitter Control R&S TCE900R&S® TMU969System Manual 2600.5423.02 ─ 01For a medium-power transmitter, the connection from the exhaust kit to the trans-mitter's control unit is established via the air cooling interface. This can be used tocontrol 2 fans independently of each other using a 0 V to 10 V voltage signal. Simul-taneously, 2 tachometer signals from the fans can be evaluated to determine theirspeed.Two differential pressure sensors (1) are used to measure the pressure inside theframe enclosure with reference to the outside air pressure. Through the ACIF of theR&S TCE900, the RPM of the two fans (2) are regulated with the aim of maintainingnormal air pressure within the enclosed frame.Two examples for controlling of the normal air pressure in the rack:– For example, when the temperature of the air fed to the transmitter rises, the RPMof the amplifier cooling fan will increase accordingly in order to adequately coolthe amplifier. As a result, the pressure within the enclosed frame will increaseand the ACIF will increase the RPM of the fans in the exhaust kit.– When the temperature of the air fed to the transmitter decreases, the RPM of theamplifier cooling fan will decrease. As a result, the pressure within the enclosedframe will decrease and also the RPM of the fans in the exhaust kit.During the initial commissioning of the system, a fallback RPM setting is configured.This setting ensures that adequate cooling of the transmitter is ensured, even if theACIF goes off-line.The air cooling interface is connected to the R&S TCE900 via USB on the backplane.In addition to this, interrupt lines are also provided, which run as a signal line(IRQSCB_OX, GPIO_OPTX_3) from the air cooling interface to the SCB/IPS1 andrun as feedback lines (GPIO_OPTX_4, F0_1PPSSCB_OX) from the IPS1/SCB to theair cooling interface.The plug position of the air cooling interface can be determined in the R&S TCE900using SLOT_IDX.●LAN switchAdditional Ethernet connections are provided using a LAN switch.In addition, connections for the R&S TDU900 display unit and additional external instru-ments (e.g. parallel remote control interface) are located here.R&S TCE900 ExcFig. 4-2: R&S TCE900 Exciter - rear view1 = RF Board2 = Coder boardIn addition to the basic unit, the R&S TCE900 Exc contains the following plug-in modules:●Coder boardThe coder board in the R&S TCE900 is used for the transport stream's (TS) basebandcoding.

The entire RF circuitry is on the A2 module(amplifier board).Broadband and Doherty mode (DTV only)Apart from conventional broadband mode, the amplifier can also be operated accordingto the Doherty principle in order to considerably improve AC efficiency (approx. 35 %).Whereas the amplifier in the classic operating mode (as a linear amplifier with class ABoutput stage) operates as a broadband unit without the need for adjustment across theentire UHF range at AC efficiency levels around 25 %, the amplifier in Doherty mode isband‑limited at efficiency levels > 35 %.The operating mode of the amplifier is set using a tuning unit ("tunit") which can beaccessed from outside and is part of the top cover. With the tunit in its normal installationposition, the R&S PMU901 operates in AB mode as a conventional broadband linearamplifier with 6 parallel‑connected BLF888 units. When turned through 180°, the tunitallows the output stage to operate according to the Doherty principle. Three BLF888 unitsthen serve as the main amplifier and three as the auxiliary amplifier of the 6 dB Dohertysystem. The tuning of the tunit now determines the available frequency range. There areseven fixed tuning ranges or tunit variants for the entire UHF band (470 MHz to 862 MHz).One tuning range covers up to 12 channels.This special patented architecture of the R&S PMU901 means that the amplifier itselfactually remains invariant. Different variants do not need to be made available as replace-ment parts. Every amplifier can be used in every transmitter. If a (Doherty) amplifier needsto be replaced, the tunit is pulled out of the amplifier to be replaced and then inserted intothe replacement amplifier. If the frequency of the entire transmitter has to be changed(very rare), only the tunits have to be changed (not necessary in all cases). If in doubt,the amplifiers of a transmitter can of course always be configured to conventional broad-band mode by turning the tunit. This operating mode is indispensable, especially in thecase of replacement transmitters in N+1 systems.A control word is used to inform the amplifier control board of the installation position ofthe tunit and therefore the operating mode. In Doherty mode, the control word alsoinforms the amplifier control board of the tuning range. If the tunit does not match the Design and Function R&S PMU901

Module A1 (amplifier controlboard), which operates independently of power and frequency band and is also used inother TX9 amplifiers, is responsible for the monitoring and control functions as well asCAN bus connection. The interface for the amplifier control board is largely compatiblewith the VH8xxx amplifiers. This means that the amplifier can be operated using thecontrol unit from the 8000 family and outside of the transmitter for test purposes usingthe GT800A1 test box.Power supplyThe amplifier has a 3 kW power supply unit (regular power supply unit 1) which deliversboth the amplifier operating voltage and the 15 V auxiliary voltage. As an option, anidentical power supply unit can be parallel‑connected as an active standby. Both powersupply units can be replaced without the amplifier needing to be switched off or removedfrom the transmitter. The standby power supply unit can be assigned to a separate phaseon the system side. The permissible mains voltage range of the amplifier is 170 V to264 V AC.At reduced output powers, the efficiency of the amplifier can be optimized by reducingthe DC voltage of the power supply.5.1.2 Mechanical DesignThe amplifier is fully enclosed in a 19" metal housing. The height of the cabinet is 3.5 HU(156 mm). The housing consists of a mounting frame, top cover, front cover and rearpanel. The two fans are attached to the rear panel. At the center of the housing is theamplifier board, under which is the heat sink and under that the power supply unit withpower adaptor board.After the mains voltage has been disconnected (after the pre‑trip has been switched off),the amplifier can be removed from the rack without disconnecting any connectors whilethe transmitter is still in operation (self-engaging plug‑in connections).Although the R&S PMU901 amplifier is normally used in combination with a transmitterrack, it can also be operated as a stand‑alone desktop unit together with the R&S TCE900exciter.ModulesThe amplifier consists of the following modules:●A1: Amplifier control board●A2: Amplifier board●A3, A4: Power supply 1, power supply 2 (standby, optional)●A5: Tunit (tuning unit) Design and Function R&S PMU901

The cooling system features the following:●The amplifier circuitry is cooled by means of thermal conduction to the heat sink whichdissipates heat to the flow of cooling air inside the amplifier (no additional fans areused).Design and Function R&S PMU901
Amplifier R&S PMU901R&S® TMU977System Manual 2600.5423.02 ─ 01●The power supply unit has its own heat sink which also dissipates heat from the powersupply unit to the flow of cooling air inside the amplifier.●Part of the cooling air also flows through the power supply unit circuitry in order tocool the components.TunitThe installation position of the tuning unit ("tunit") determines whether the two groups ofthree identical output‑stage transistors are parallel‑connected to form a classic broad-band amplifier or whether they form a Doherty system with a main and auxiliary amplifier.●With the tunit in its normal installation position ("B‑Mode" on the top cover), theamplifier functions as a conventional linear amplifier with 6 parallel‑connected out-put‑stage transistors in AB mode. It thus operates as a broadband unit without theneed for adjustment across the entire UHF range.●When turned through 180° ("D‑Mode" on the top cover), the tunit allows the outputstage to operate according to the Doherty principle. Three output‑stage transistorsthen serve as the main amplifier and three as the auxiliary amplifier of the 6 dB Doh-erty system. In this operating mode, the two tuning elements of the tunit determinethe operating frequency(-ies) of the amplifier. They are indicated on the tunit labeland are only valid for as long as the calibration sticker is undamaged.The tunit is inserted from above into the cover of the amplifier section in the amplifier. Itis therefore only accessible when the amplifier has been removed from the transmitter.The amplifier must be switched off before the tunit is removed! Removal while the ampli-fier is still in operation can result in the transistors being irreparably damaged.5.1.3 Display Elements and Interfaces5.1.3.1 LEDs and Test Point – Front PanelThe following LEDs for indicating states and faults are on the front panel: Design and Function R&S PMU901

This allows evaluationof the signal quality downstream of the amplifier.The coupling attenuation of the RF MONITOR test point has a frequency response of-6 dB per octave. The attenuation at 650 MHz is stored and can be queried via the trans-mitter control unit. The level at X3 changes slightly (approx. 0.1 dB) if a connection isdisconnected or connected at X13 (ADE OUT, rear panel).5.1.3.2 Connectors – Rear PanelThe following connectors are on the rear panel of the amplifier:●X1 – Mains voltage feed for 1 or 2 power supply units●X2 – HF output RF OUT(7/16 female connector)●X10 – HF input RF IN(SMA female connector)●X11 – AMPLIFIER CONTROL interface to the amplifier control board with integratedconnection to the CAN bus (D‑Sub male connector, 15‑contact)●X13 – Second ADE OUT RF test connector for connecting the ADE demodulator forautomatic digital precorrection upstream of the channel bandpass filter (with 1 ampli-fier in the transmitter; SMA female connector)●X22, X23 – Connection for fan 1 and fan 2 (Molex male connector)●3 connection possibilities for the additional PE conductor (a second PE conductor isalways required!)

It goesthough the following steps in the preamplifier and driver.●The RF input signal passes from the amplifier input X10 on the rear panel of theinstrument along the RF line W10 and into the preamplifier, which is under anRF‑shielded cover.●In the preamplifier, the signal passes through the following components in sequence:– Amplitude regulator– Small‑signal amplifier– Phase regulator●This is followed by an LDMOS transistor stage (BLF642, single‑ended, A mode) asa preliminary driver. Design and Function R&S PMU901
Amplifier R&S PMU901R&S® TMU982System Manual 2600.5423.02 ─ 01●The signal leaves the preamplifier and is fed to the input of the driver amplifier via thecable W145x. This input consists of two single‑ended LDMOS transistor stages whichare interconnected by means of 90° jumpers. The two transistor halves of theBLF888B push‑pull transistor are used for this purpose.●The cable W145x is also used for phase adjustment (in the case of design modifica-tions or for tolerance adjustment). It connects the connectors X301 and X400.●The output signal of the driver is fed to the output‑stage splitter via a harmonic filter.This filter is used especially at low frequencies to suppress the first harmonic.The cable W145x must not be removed and should only be replaced with a cable withthe same R&S part number. Failure to observe this point can result in destruction ofabsorbers of the power combiner in the transmitter (if more than one amplifier is installed).5.1.4.3 Signal Gain in Doherty-Capable Output StageThe output stage is divided into two groups, each with three transistors. In Doherty mode,one group forms the main amplifier (3 x BLF888B) and the other forms the auxiliaryamplifier (3 x BLF888A). If the two groups have equal priority, however, they can alsoform a conventional output stage.The following steps take place in the output stage:●The output signal of the driver is fed via a 90° splitter to two output‑stage groups eachwith three transistors.●The two power streams are divided between the three transistors of each out-put‑stage group via a 0° splitter. The output‑stage group which forms the main ampli-fier in Doherty mode uses BLF888B transistors, and the output‑stage group for theauxiliary amplifier uses BLF888A transistors.●Two 0° combiners combine each group of three partial power streams and make themavailable at the inputs of a 2‑way power combiner ready for addition.●The tunit connected at the power combiner determines the operating mode of theamplifier:– Conventional broadband AB mode in the normal installation position– Doherty mode if the tunit is turned through 180°●Directional couplers upstream of the RF output of the amplifier (downstream of the2‑way power combiner) detect forward and reflected power. Their signals are fed toRF detectors. A further directional coupler provides two free decoupled RF test points(RF MONITOR, ADE OUT) via a small splitter.The operating points of the transistors of the main and auxiliary amplifier can be setseparately. In Doherty mode, the main amplifier operates in AB mode and the auxiliaryamplifier in C mode. When the amplifier operates as a conventional broadband amplifier,all of its output‑stage transistors operate in AB mode. Design and Function R&S PMU901
Amplifier R&S PMU901R&S® TMU983System Manual 2600.5423.02 ─ 015.1.4.4 Power ControlTo ensure that the required power is always present at the amplifier output, the leveltolerances at the following points are adjusted by means of a power control circuit.●at the amplifier output●at the entire RF amplifier stageDuring power control, a control amplifier which is on the amplifier board (module A2,preamplifier section) is supplied with an actual voltage and a nominal voltage. The nom-inal voltage is the VREF_PWR signal which is fed as a CAN command and is used toadjust the output power.Intelligent control brakeIn the case of the R&S PMU901 with the special output‑stage architecture necessary forthe Doherty operating mode, it is not possible to apply the control principle with transis-tor‑failure tolerance which is traditionally used at Rohde & Schwarz and features twoindependent actual value detectors downstream of the subamplifiers with the same out-put power.The PWR_OUT signal which is proportional to the sum output power is used as the actualvalue for control. In order to still retain tolerance with regard to transistor failures, theprinciple of the "intelligent control brake" is applied (IPLIM = Intelligent Power LIMiter).Here, the adjustment range of the control amplifier is simply limited adaptively in such away that overloading of the intact transistors in the event of a transistor failure cannotresult in their failure. The control brake therefore always adapts to the current conditionsin the control circuit. This principle exploits the fact that changes in gain and input signalwhich are the result of temperature and aging take place only slowly.The manipulated variable (the regulating voltage of the PIN attenuator) is recorded atlong intervals. The control brake (i.e. the maximum possible value for the regulating volt-age) is derived from the measured value plus the difference which is not exceeded untilthe next measurement, provided that normal temperature and aging processes exist. Thismeans that the control brake will also increase slowly if, for example, the gain drops withincreasing temperature and the regulating voltage of the PIN attenuator increases in orderto maintain the output power. In the case of dramatic changes resulting from transistorfailure or dramatic changes in the input signal, adaptation of the control brake with respectto this is stopped and the control brake thus becomes fully effective.The amplifier control now analyzes the current situation without disturbance andresponds according to the determined cause. If the cause is, for example, a transistorfailure, the amplifier control adapts the nominal regulation value according to the remain-ing performance of the amplifier. In this way, a stabilized condition is achieved, albeit withreduced output power. At power ON and if the nominal regulation value is changed, thecontrol brake is of course stopped briefly.Reflected power test pointIn the case of reflection at the amplifier output, the forward power is reduced in order toprotect the amplifier. For this purpose, the REFL_SAVE signal is acquired at the reflectedpower test point. This signal is superimposed on the actual value signal during powercontrol by means of a diode. If the REFL_SAVE signal exceeds the voltage of the forward Design and Function R&S PMU901
Amplifier R&S PMU901R&S® TMU984System Manual 2600.5423.02 ─ 01power detector PWR_OUT, the reflected power test point takes over power control. Thecontrol amplifier supplies the control voltage V_REG as the output quantity and this volt-age is fed to the amplitude regulator in the preamplifier.Additionally, the REFL_OUT signal is acquired at the reflected power test point. Thissignal together with the PWR_OUT signal (forward power) is used for VSWR indicationat the amplifier output.5.1.4.5 Self‑Protection MechanismsThe amplifier has a series of self‑protection and monitoring mechanisms which protect itagainst irreparable damage in the case of impermissible operating conditions and enabletransmission to continue for as long as possible. The following mechanisms are available.●Power supply monitoring●Input level monitoring●Output power limitation●Temperature monitoring incl. fan control●Reflection monitoring●Operating mode monitoringPower supply unit monitoringThe power supply unit has the following self‑protection mechanisms:●Overtemperature shutdown for the duration of overtemperature●Short‑circuit current limitation●Input voltage monitor (enables shutdown to limit the input current in the case ofundervoltage)●Overvoltage limitation (on DC side)If no standby power supply unit is installed, failure of the power supply unit (/DC_OK = high) will mean failure of the amplifier. If a standby power supply unit is installed,there will be no operational restrictions. The amplifier will however be completely deac-tivated if both power supply units fail.The overtemperature shutdown in the power supply is intended purely as a self‑protectionmechanism only and is not indicated by the front LED as the DC voltage is switched off.A temperature shutdown at the power supply is signaled only indirectly by the message /DC_OK_x. The power supply unit has status LEDs for normal operation and fault indi-cation. These LEDs are indirectly visible after removal of the front cover (and, whereapplicable, the air filter).Input level monitoringIf the input level drops below a defined threshold (RF_IN_FAIL), power control is influ-enced by the following measures:●The amplitude regulator for power control is switched to maximum attenuation●The internal reference voltage for power control is suppressed Design and Function R&S PMU901
Amplifier R&S PMU901R&S® TMU985System Manual 2600.5423.02 ─ 01A soft start is performed as soon as the input signal returns. The selected threshold issuch that the amplifier can be reliably operated across the entire temperature range inall permissible operating modes, even at the lower tolerance limit of the RF_IN inputsignal at X10.Output power limitationThe output power is set by means of the VREF_PWR signal. The output power is limitedsuch that the amplifier cannot be damaged at excessively high VREF_PWR values. Inaddition, the average output power of the amplifier is also limited by means of hardware.Excessive power if the forward power test point fails as well as subsequent failures if atransistor fails are countered by the intelligent control brake.Temperature monitoring and fan controlThe power supply units and amplifier circuit each have a dedicated hardware overtem-perature shutdown mechanism. If a temperature threshold is exceeded, the amplifier isdisabled (TEMP_FAIL message), whereby the threshold for the overtemperature shut-down is above the permissible operating temperature. This ensures that the remainingoverall power loss does not lead to overheating of the instrument, even with total failureof the cooling system.The fan has four different speed settings, whereby the second speed is the standardspeed which has been optimized with regard to the average junction temperature of theoutput stage and to noise generation.To ensure that transmission can continue for as long as possible, the temperature andfan control functions work together as follows:●If the temperature rises in the amplifier circuit, the fan speed is first increased beforethe hardware shutdown threshold is reached.●If this is not enough, at temperatures above 83 °C the amplifier control begins toreduce the output power in steps of 1 dB (DTV only, REDUCED_PWR message).●With ATV, the output power is not reduced at excessively high temperatures. Instead,the amplifier is shut down by means of software at 85 °C.●At temperatures above 90 °C, the amplifier remains switched off by means of hard-ware for as long as the overtemperature exists. Overtemperature on the amplifierboard is indicated by means of the front TEMP FAIL LED (with ATV: at 85 °C andhigher).●An appropriate hysteresis is integrated to prevent deactivation and activation fromoccurring too soon. A soft start is performed as soon as power returns.In addition, the inlet and outlet temperature is measured by means of two sensors (onthe front and rear side of the amplifier board, thermally insulated from the rest of theprinted board). This allows, for example, a fouled air filter to be detected and changed ingood time (AIR_FILT_FAIL message).Reflection monitoringA distinction is made between the following types of reflection monitoring (REFLECTIONmessage):Design and Function R&S PMU901
Amplifier R&S PMU901R&S® TMU986System Manual 2600.5423.02 ─ 01●With major reflection above reflection threshold 2 (s = 2), the power is briefly cut offcompletely first of all; a soft start is performed immediately afterwards. If any reflectionremains, the amplifier protects itself by reducing the output power. The time constantselected for the shutdown is such that damage to the amplifier is prevented in thecase of total reflection and at all phase angles of the reflection at X2.●With weaker reflection above reflection threshold 1 (S = 1.5), the output power isreduced without preceding shutdown.●When reflection no longer exists, the power reduction is canceled automatically.Operating mode monitoringUsing a 5‑bit code (FREQ_ID), the transmitter notifies the amplifier of the expected oper-ating mode and, in Doherty mode, the expected tuning variant (transmit frequency). If thiscode is not the same as the code of the tunit installed in the amplifier, the amplifier ignoresthe ON command and signals FREQ_FAIL.For conventional broadband operation, the FREQ_ID is 00000. If no tunit is installed, theamplifier signals FREQ_ID 11111. All other FREQ_IDs are reserved for Doherty mode.5.1.4.6 Emergency ShutdownThe amplifier can be disabled externally by means of the SHUT_DOWN signal at X11,for example to ensure self‑protection for the absorber of the power combiner in the trans-mitter. The signal, which is immune to cable breaks, is fed via an optocoupler onCAN_GND and is therefore insulated from amplifier ground. The output power is sup-pressed for as long as no connection to CAN_GND exists.To activate the amplifier when the R&S GT800A1 test box is being used, it is necessaryto connect X20 (GND) to X21 on the test box.5.1.5 Specifications5.1.5.1 General DataFrequency range 470 MHz to 862 MHz (band 4 and 5)Power supply (3 separate phases) - Nominal voltage range 200 V to 240 V- Tolerance range 170 V to 264 V- Nominal frequency range 50 Hz to 60 Hz- Tolerance range 47 Hz to 63 HzPower factor (cosφ)≥0.98 at nominal power Design and Function R&S PMU901
