3. LDMOS HF amplifier 1200W output BLF188XR 1.8-54 MHz
This a ready power amplifier. You will need a case and power supply only!
Water-cooled hermetically. You can turn the power amplifier. The water will not flow.
The power supply may be for example: FlatPack2 HE
Transistor BLF188XR 1 pcs.
100W input power with ATT
Output power 1200W (SSB/CW)
Two levels of blowing. Running the second level at a copper radiator temperature is more than 50 degrees Celsius. Stop transmission for copper radiator temperature is more than 80 degrees Celsius.
Supply voltage 53V
Voltage 13.8V 1.5A
Protection in power output
Protection against spontaneous or incorrect switching LPF.
LCD - out power and VSWR
LED indication of protection operation by SWR, current and maximum output power.
Installed on the cable output SO-239
TRX cable SO-239
Control 25 pin connector
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.
Size 240 mm x 260 mm x 140(h) mm
