100W RF power amplifier circuit built with 2 BLY94 transistors. If you want to see more rf amplifiers check the list bellow.
Components:
Active components: BLY94
Coaxial cable length : K x Lambda / 4, where K = 0.66 for 50 ohm cable and K = 0.8 for 75 ohm cable.
This fm rf power amplifier circuit is built with BLY94 transistor which delivers up to 50W at 175MHz and has a power gain of 7dB, arround 5x power amplification.
But in this schematic bly94 is working in 3 meter band, FM 88-108 MHz, so it has a higher power gain, 8dB – 6x. So if we use a good quality trimmers and coils with 7W input rf power BLY94 will deliver up to 50W rf power. If you use it in C class dont connect R1.
BLY94 is a RF power transistor in a SOT-55 case which operate in class-B with a Vce of 28V and a frequency transition of 175MHz.
BLY 94 output power is 50W with a 7dB ( 6x ) power gain at 175MHz.
