The RF signal coming from the main card reaches the pilot is amplified and is then sent to the final stage that sees to its final amplifications up to 30VV The amplifier is made in three stages The first is made with two BFR540s in parallel the second with one BLF244 and the last with one BLW86 n addition to the actual RF amplification this circuit carries out the follovving functions Control of the power level in output depending on the setting Reduction of the power supplied when there are high levels of reflected power Measures direct and reflected power through directional couplers Measures current absorbed by the power amplifier Measures temperature Low pass filtering of the RF signal in output On this card is an RF sample approximately 30dB compared with the output that is available on a BNC connector underneath the output connector of the transmitter This sample is useful for checking the characteristics of the carrier but not of the higher order harmonics 8 5 Telemetry board This device is designed to furnish to the user the the state of operation of the machine All the available input and output signals are replied on the DB15 connector On the same board there is also the BNC connector of interlock for disable the device Closing the central pin to ground the exit power has reduced to zero until the connection it doesn t come removed When it is used with a R V R amplifier this connector

34. dB Another important feature the TEX LCD has is its great simplicity of construction and use For example the mains power supply is universal type and allows any voltage between 90 V and 260 V to be used without having to select it manually The TEX LCD was designed to be modular Its various functions are run from modules directly connected to each other with male and female connectors or with flat cables ending in connectors This type of design makes maintenance operations and any required module replacement easier All models are made with SMD technology This exciter contains a low pass filter that reduces the harmonic emissions to below the limits allowed by international regulations and can therefore be used as a transmitter connected directly to the antenna The machine is offered in two versions one for Mono or MPX input wideband input that is useful when you want to transmit in stereo using an external stereo encoder and the other with an integrated stereo encoder The TEX LCD stereo encoder guarantees excellent stereo separation together with a low harmonic distortion level Also the stereo version of the exciter can be configured for operating in Mono MPX mode meaning excluding the stereophonic coder and using the left input as the mono input and the BNC as the MPX The user can do the configuration through microswitches that are accessible from the outside Both versions have two inputs SCA1 and SCA2 for modulated s
