LDMOS HF amplifier 1W(or 0.5W) input 1000W output BLF578 1.8-54 MHz
LDMOS HF amplifier 1W (or 0.5W) input 1000W CW SSB output 1.8-54 MHz
This a ready power amplifier. You will need a case and power supply only!
The attenuator is not included in the kit. It is necessary to establish independently. The choice of the attenuator value depends on the output power of the transmitter.
Attention! It is necessary to use a transmitter with a full output power. ALC emissions can damage the transistor.
Water-cooled hermetically. You can turn the power amplifier. The water will not flow.
The power supply may be for example: FlatPack2 HE
Transistor BLF578 1 pcs.
Transistor are installed on a copper radiator with liquid metal "CoolLaboratory Liquid PRO"
You can buy a housing like this: http://www.ebay.com/itm/121995534231?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Input power - 1W (0.5W other option)
Output power 1000W (SSB/CW)
This tube is sufficient for cooling, because The internal area of the tube is L=PD
