Application Note Read carefully Application note before use. For any additional information or suggestion please contact TDE technical staff. Note 1 cooling system requirements Cooling system must assure that amplifier will work in safety conditions. This amplifier is self protected against high temperature, however we raccomand to use the amplifier at lower temperature as possible, this because lower temperature means a better MTBF. Please be sure that heatsink surface is cleaned and very smoothed, be also sure to use a good quality thermal compound between flange and heatsink. High power concentrations means that is not easy to dissipate the power in case of work at full power CW for long time. In case that your application foresee to work more than 2/3 Min continuously in this condition we strongly recommend a water cooling system.

Note 2 (Load matching) This amplifier use the rugged RF device on the market, it can work without power reduction on a load with 3:1 of VSWR. Anyway we recommend to foresee an appropriate protection system able to switch off the power in case of excessive power reflection. Note 3 (quiescent current) Quiescent current is set in factory at about 1 amps (0.5A for device). Note 4 (shielding) Due to the High gain of this pallet, is required a good isolation between output power section and any driver stage mounted inside the same rack.
Note 5 (CW applications) Due to the high linearity of devices, this amplifier is capable to deliver more than nominal power in case of overdriver. Please avoid to overcom the nominal power because this can destroy the matching element on the output section. It is a good practice to use a current limited power supply, to assure the safety operation. In case of work in CW for long time please read the note 1 Note 6 (Efficiency) To improve the efficiency is a good practice take the input power at the maximum level and adjust the output power by means reducing supply voltage, in case that your application allow this solution the efficiency can improve of about 10% in many parts of band.
