HF with 50 MHz power amplifier 1200W LDMOS BLF188XR Heat pipes
Supply voltage + 50V 34A. Operation bands 160 6 meter. Protection High SWR, high output power. High drain current, overheat 80C. Cooling system Heat pipes 6 pcs 8mm diameter. Size 240 x 235 x 220 mm. This amplifier use BLF188XR LDMOS transistors. It is equipped with all protections required for safe operation. SWR on output higher than 2.0:1. It has two levels of air cooling fan speed: normal and forced. Forced mode is engaged when copper heat spreader plate temperature rise above 50C. If temperature rise above 80C the PTT line is being disabled. Both thermo sensors has 10C hysteresis. Two lines LCD shows the output power in Watts and SWR on output. Second line is output power bar graf. Protection status LEDs are placed on boards, but could be transferred to the front panel. Rear side has 2 coaxial connectors (input and antenna) and 25-pin control. The control connector is used to select the LPF bands and has +13.8V, ALC and PTT inputs also. 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 + 50 - 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. 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. The amplifier is assembled on aluminum frame, easy to place inside the box of suitable size.
