Product Description

300W HF AMP COMPONENT SET

This amplifier design covers frequencies from HF to VHF with a power output level of 300 watts using RF power MOSFETs. The MRF141G used in this design is considered as a state of the art device. The MRF141G is housed in a special push-pull header commonly known as "Gemini" (twins) meaning that there are two identical transistors mounted next to each other on a common carrier or flange. The frequency range of this amplifier design is 10-150 MHz. This amplifier was originally designed for operation from a 12 to 28 volt power supply. As the MRF141G is basically made for operation from a 28 volt supply, lowering the voltage down 20 volts or lower would make the unit almost indestructable against load mismatches such as open coax or a broken antenna.
