This is a 2 meters 144 Mhz rf amplifier wich works in push pull and is build with DV28120T Vmos.
You can use coils made form RG142 coaxial cable or similar, 620mm long , 5mm diameter, 6 turns with inside diameter 30mm no gaps between.
2 meters 144MHz push pull amplifier wich can generate 200W, how does it sound ? Sounds delicious with 2 DV28120T transistors.
The 10 meters 27MHz CW radio amplifier is equiped with VN66AF transistor produced by Siliconix wich has some advantages: its cheap, great dielectric insulation and high gain. Here we use VN66AF as an rf amplifier for 10m band (26 … 30 MHz ).
This fm 88-108 Mhz radio amplifier is equiped with BLF 245 and can be user with a heatsink from a processor and cooler.
