Blf188xr 1kw Linear Amplifier Module On Pure Copper Heat Sink
The board is double sided plated G-10 copper (high current board). Board is tested and adjusted for class AB of operation. The XR is extremely rugged. It will withstand 65:1 VSWR!!!!!!(full short at full power). A temperature regulated bias circuit and a high power transmission line transformer for low loss and wide bandwidth are provided. Also n egative feedback for better IMD and gain flatness is used.
Peak CW power 1300 W. Efficiency at CW Peak power(1415W) 81.4%. Power Gain at P3dB 29.1dB!! I drain at P3dB 31.6A. Vbias: 12V for keying the amp.
Gain is very high so with FB I lowered the gain to get far better stability. The cores are large and many thus an.Average rise of cores temperature is also minimized. As a result I have not.
