Gambar Amplifier Pemancar FM power

Gambar Amplifier Pemancar FM power - Rangkaian Power Amplifier Pemancar FM tergolong simple dan sederhana, kualitasnya cukup bagus. perlu di coba untuk pembuatannya ( detail lihat gambar di bawah ini.), berikut teori dan penjelasannya :

A very simple fm power amplifier which can deliver 4W rf power with 12V power supply and BLY87A or KT920A and 20W with BLY89A or KT925B. If you use BLY87A or KT920A the input power must be 0.5W and 4W if you use BLY89A or KT925B. This fm power amplifier is designed to work on 50 Ω antennas and a maximum power supply of 14V and in 88 108 MHz band. Use only metallic trimmers, a good heatsink for the transistor and ceramic capacitors and keep the pins very short.

• C1 = C8 = 10-40pF + 22pF in parallel ||
• C2 = 10-70pF + 120pF ||
• C3 = 2.2nF
• C4 = 33nF
• C5 = 4 x 180pF
• C6 = 1nF
• C7 = 2.2nF
• C9 = 10-70pF + 47pF ||
• R1 = 380Ω
• R2 = 47Ω
• R3 = 5.6 Ω
• L1 = 3 turns / 0.8mm / 6mm / legth = 8mm
• L2 = 6turns / 0.5mm /over R2
• L3 = 5 t / 0.6mm / 6mm
• L4 = 4 t / 1.2mm / 8mm
• T = 4W with BLY87A, KT920A
• T = 20W with BLY89A, KT925B
