3 ~ 30 MHZ, 50 WATT POWER AMPLIFIER

  • Estimated cost : Rp.200.000 (USD 20)
  • Condition : Homebrew, with all components available at local market


Personal review :
  • Broadband Linier RF amplifier from 3 ~ 30 MHz (FM, AM/SSB)
  • Power input 50 mW ~ 1 Watt
  • Power Output 50 Watt maximum at 12.5 VDC, 8 Amperes
  • Power transistor 2 x 2SC1969
  • very useful as portable booster for Remote control transmitter (below 40 MHz), 11m/27 MHz walkie talkie or Citizen Band, etc.
  • Easy to build, no tune required, however additional filter might be required for permanent operation to avoid interference to TV.

Boss, sekarang cari transistor 2SC1969 susahnya minta ampun, Jangankan yang asli Mitsubhisi, yang palsu seperti 2SC1969 SK juga sisah didapat. Bagaimana ini boss?
