The output power is 1.0 - 4.0 Watt adjustable (carrier only). The amplifier operatesover 118MHz - 138 MHz frequency range without tuning.Output filtering for the VT-3A130 Amplifier is provided by an Output Lowpass Filter Board. TheOutput Lowpass Filter Board is mounted in a separate compartment of the amplifier case in order toprovided maximum attenuation of harmonic and other spurious signals.Refer to section 4.1.2 "VT-3A130 Amplifier Schematic Diagram" for the Amplifier schematicdiagram and section 4.1.3 for the Output Lowpass Filter component layout and schematic diagram.1.2 Performance SpecificationType: VT-3 series VHF Amplifier moduleFamily: VT-3A130Frequency Range: 118.0 MHz to 138.0 MHzRF Power Output: 1.0 - 4.0 Watts adjustable (carrier only)RF Power Input Nominal level from -5 dBm to +5 dBmSystem Impedance: 50 ΩSpurious and Harmonics Emissions: More than 90 dB below carrierModulation: 6K00A3 (Amplitude Modulation)Transmitted Noise More than 45 dBc below carrierAudio Response: Flat audio; +1/-3 dB: 300 Hz - 3 kHzAudio Distortion: Less than 3% -40˚C to +60˚C at 30% modulationLess than 5% -40˚C to +60˚C at 90% modulationLoad VSWR tolerance: Z load = 20:1:Operating Voltage: +13.8 Vdc Nominal (range +10 to +17 Vdc),+9.5 Vdc Regulated.Active Current: +13.8 Vdc supply less than 1.5 A at Pout=4Standby Current: Typically less than 4 mA

DE DANIELSELECTRONICS VT-3A130 Amplifier Instruction Manual 2-12 THEORY OF OPERATION2.1 GeneralVT-3A130 Amplifier is a Class A linear amplifier with a low level AM modulator. A built inregulated power supply provides approximately 15.0Vdc output voltage with the input voltagerange of 10.0 Vdc to 17 Vdc. This amplifier utilizes a 10 Watt hybrid power amplifier modulemanufactured by Mitsubishi. The module is mounted directly to the heatsink with its leads solderedto a circuit board where DC supply voltage and RF input and output connections are made.Power for the VT-3A130 Amplifier is provided from +13.8 Vdc and 9.5Vdc supplies. Thesupplies can be continuously connected to the amplifier. The VT-3A130 Amplifier will draw onlyabout 4 mA of current from +13.8 Vdc and about 0.1 mA from 9.5Vdc until the AMPLIFIERENABLE pin is grounded.The VT-3A130 Amplifier is housed in a machined aluminum case that ensures optimum RFshielding, provides a good ground, and also acts as a heatsink.2.2 Power RequirementsThe current drawn from the +9.5 Vdc supply should not exceed 10 mA. Current consumption ofthe +13.8 Vdc line is dependent on transmitter frequency, output power, temperature, and supplyvoltage and can range from 800 mA to 1500 mA. The current drawn from the +13.8 Vdc supplyshould not exceed 1500 mA under normal circumstances and should never be allowed to exceed1700 mA.2.3 RF CircuitryRefer to Section 4.1.2 "VT-3A130 Amplifier Schematic Diagram". The RF input signal with alevel of -5 dBm to +5 dBm is fed to the VT-3A130 Amplifier Board and then is modulated by abalanced AM Modulator which consists of Q1, Q3, Q4, and a wide band RF transformer XFMR1.Q1, Q3 collectors are supplied by 15.0 Vdc in order to increase the modulation linearity. On thecontrary, the base circuitry of Q1, Q3 and Q4 are biased by 9.5 Vdc. The typical output powerfrom the Modulator is about 3dBm to 5 dBm. The signal is then amplified further by a HybridPower Amplifier Module U1, which is the class A, 10 watt linear amplifier. The U1 is suppliedfrom a 15.0Vdc internal regulated power supply. Maximum carrier power output is 4 - 5 watt forthe input voltage range from 10 Vdc to 17 Vdc. Output filtering for the VT-3A130 Amplifier isprovided by a Low Pass Filter Board. The Low Pass filter assembly is mounted in a separatecompartment of the amplifier case in order to provided maximum attenuation of harmonic and otherspurious signals. Refer to Section 4.1.1 "VT-3A130 Amplifier Component Layout"
DE DANIELSELECTRONICS2-2 VT-3A130 Amplifier Instruction ManualThe part of the output RF energy is coupled by a directional detector circuit TL1 which provides ameans of linearization of the audio and leveling of the output power over the frequency range 118MHz to 138 MHz.The AC coupled audio signal is applied to the inverting input of U4a in order to providepredistortions to the input modulation audio signal, which is supplied from the audio amplifier U2to the non-inverting input of U4a.On the contrary the DC coupled part of the detected audio is passed through the 50Hz low passfilter U6a, U6b, and than compared with a certain DC level which is set by R19. The difference ofthe signals is amplified by U4b and applied to pin 2 of the Power Amplifier Module in order tokeep the output power relatively constant over the frequency range of 118MHz to 138MHz.2.3.1 VT-3/150 Lowpass FilterThe VT-3/150 Output Lowpass Filter is a 50 ohm, 6 pole, reciprocal filter with a 3 dB cutofffrequency of approximately 150 MHz. The low pass filter assembly attenuates the desired signal'sharmonics as well as any other out-of-band emissions so that a 'clean' RF signal is output to theantenna connector.2.4 Power Supply Circuitry.The VT-3A130 Amplifier has shutdown circuitry based on Q2 that allows decrease powerconsumption, less than 0.1 mA from 9.5Vdc, in standby mode. The voltage level on the amplifierenable line of less than +2.0 Vdc turns on the transistor Q2. Q2 supplies the base circuitry of Q1,Q3, Q4, and operational amplifiers U2, U4, and U6.The U3 LM2588 used as a step-up (boost) regulator. This is a switching regulator that produces anoutput voltage greater than the input supply voltage. The following is the LM1084ADJ, a lowdropout voltage (LDO) positive adjustable regulators with a maximum dropout of 1.5V at 5A ofload current. The LM1084 used as a postregulator that reduces the ripple current and also preventsthe output voltage level from overshooting the maximum of 16Vdc.
DE DANIELSELECTRONICS VT-3A130 Amplifier Instruction Manual 3-13 VT-3A130 AMPLIFIER ALIGNMENT3.1 GeneralConnections to the power supply, audio input and transmit enable line are clearly marked on theamplifier case. The amplifier is enabled when the enable line (AMPLIFIER ENABLE pin) isgrounded.If the amplifier is installed in the transmitter, alignment is simplified by using the SR-3 Subrack,SM-3 System Monitor, and RF extender cable to provide transmitter power and signalinterconnection (see the Transmitter Main Board Manual for details). For complete transmitteralignment, the Transmitter Main Board, Synthesizer, Amplifier, and Audio Processor should betuned in the aforementioned order. Please refer the corresponding manuals for each module.3.2 Repair NoteThe VT-3A130 Amplifier is mainly made up of surface mount devices which should not beremoved or replaced using an ordinary soldering iron. Removal and replacement of surface mountcomponents should be performed only with specifically designed surface mount rework and repairstations complete with ElectroStatic Dissipative (ESD) protection.When removing Surface Mount Solder Jumpers, it is recommended to use solder braid in place ofmanual vacuum type desoldering tools when removing jumpers. This will help prevent damage tothe circuit boards.3.3 Printed Circuitboard Numbering ConventionTo ease troubleshooting and maintenance procedures, Daniels Electronics Limited has adopted aprinted circuitboard (PCB) numbering convention in which the last two digits of the circuitboardnumber represent the circuitboard version. For example:• PCB number 43-9120 10 indicates circuitboard version 1.0;• PCB number 50002- 02 indicates circuitboard version 2.0.All PCB's manufactured by Daniels Electronics are identified by one of the above conventions.
