    1 Watt FM Amplifier Circuit This is a 1 watt fm amplifier with a good design that can be used to amplify a rf signal in the 88 – 108 MHz band. It is very sensitive if you use good rf power amplifier transistors, trimmers and coils. It has a power amplification factor of 9 to 12 dB (9 to 15 times). At an input power of 0.1W the output will be 1W....
    VMOS 144 MHz Push Pull DV28120T Amplifier 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. VMOS RF amplifier circuit...
    2M 144MHz Push Pull Amplifier DV28120T 2 meters 144MHz push pull amplifier wich can generate 200W, how does it sound ? Sounds delicious with 2 DV28120T transistors. DV28120T push pull amplifier circuit...
    27MHz CB Amplifier Circuit 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 ). With this 27MHz rf amplifier, small transmitters ~ 200mW, can be transformed in...
    BLF245 FM 88-108 MHz RF Amplifier This fm 88-108 Mhz radio amplifier is equiped with BLF 245 and can be user with a heatsink from a processor and cooler. The BLF 245 Datasheet can be downloaded over here -> blf245-datasheet BLF245 amplifier circuit...
    88 108 MHz 40W Wideband RF Amplifier MRF171A One wideband fm power amplifier designed with MRF 171A MosFet transistor. The output rf power is somewhere around 40W , the gains is 20dB ( 100 X ) . The input rf power is...
