HF amplifier 1200W output 2x2 VRF2933 1.8-54 MHz
HF amplifier 10-12W input 1200W CW SSB (1000W AM/FM digital modes) 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 VRF2933 4 pcs.
Transistors 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 - 10-12W
Output power 1200W (SSB/CW)
