SENSOR 600W 1200W 2000W FM TRANSMITTER High Performances & Fully Customizable TRANSMITTER QUICK START On the SENSOR Series Transmitters the Output power must be set exclusively from the CELL 2000 Amplifier. The output power of the SYNAPSE 30/50 Exciter must be set fixed at 10W and is not necessary to change, moreover, keeping it at 10W the maximum performances in terms of efficiency are achieved. The sequence is: MAIN MENU-PROGRAM MODE-FW PROGRAM-FWD SET The steps to set the power from the CELL 2000 are as follows: • Start from the Main menu • Go to the menù PROGRAM MODE and push Enter • Go to the menù to set the power and push Enter • Set the power with the keys Up and Down and push Enter Press ESC to return to the Main menù CONNECTIONS SENSOR 2000 ATTENTION PLEASE CELL 2000 has a HIGH GAIN input so it needs only 800mW to work as power driving. So it’s very important don’t put higher power in the input to avoid the risk of damage of the input amplifier. For this reason is provided togheter with the transmitter an 10dB attenuator and it’s mandatory this is connected to between the ouput of the exciter and the input of the amplifier. This is one of the biggest highligths of this kind of transmitter, in fact: 1) The exciter works always over a 50 Ohm load. 2) The amplifier has always perfect 50 Ohms input amd, because it’s handle only 800 mW it’s capable to turn internally ON/OFF the input power in case of protection of the output amplifier.

In this Video we try to explain with this video an easy way to verify if they are good or broken. We think to do this tutorial because the LDMOS are Efficient, Robust but Complex Devices and even the simplest of operations like testing a good mosfet from a bad one is never an easy task especially for the beginners in the field. Typically the LDMOS, very robust from the part of the Drain are more weak on the Gate side. A fast way to know is it is defective is measuring the ohmic resistance between: Source and Gate and between: Source and Drain. The resistive value must be high, very high (several MOhm or infinite) . On the other side, when the LDMOS is broken this value change really significantly e becomes of few KOm or even few Ohm. Because the LDMOS are paired inside, it's always possible to compare both sides of it. Many times, one half of them is broken while the other half is good. The best way to do this meassure is to unmount the LDMOS, but good results can be achieved measuring it with the complete RF Amplifier. In this case, the values are highly affected by the components on the circuit but, if one half of the LDMOS is really in short circuit it's easy to find the difference with the half good one.

LDMOS are Efficient but Complex Devices, we try to explain with this video an easy way to verify if they are good or broken. Typically the LDMOS, very robust from the part of the Drain have problems on the Gate, and, a fast way to know is reassuring the resistance between drain and source is high, very high. On the other side, when the LDMOS is broken this value change really significantly. Because they are paired inside, it's always possible to compare both sides of the LDMOS.

MOSFETs are outstanding devices when it comes to amplifying or switching of various kinds of loads. Though transistors are also largely applied for the above purposes, both the counterparts are hugely different with their characteristics. Even the simplest of operations like testing a good LDMOS from a bad one is never an easy task especially for the beginners in the field. With this method we test hundreds of LDMOS with always good result.
