Power amplifier protection device:
Protection from exceeding the output power of 1200 watts.
Protection against exceeding the maximum drain current of the LDMOS transistor.
Protection against overheating - two thresholds of operation:
when the copper radiator is heated more than + 50С - the accelerated mode of the fan operation is activated to increase the heat removal.
when the copper radiator is heated above + 80 ° C, the protection system trips, breaking the PTT circuit. Transmission is not possible.
Protection against exceeding the SWR more than 2.0: 1. The activation of the SWR protection is independent of the output power level
Protection against false / spontaneous band switching in LPF.
The activated protection channel is indicated by a lit LED on the front panel of the power amplifier. To reset the error, it is necessary to switch off and on again the power supply of 48-53.7 V.
