10 Watt Single Band Amplifier Kit


Our 10 watt single band amplifier kit is designed to increase the power output of low power transmitters It provides approximately 15dB gain and includes an input attenuator that can be configured to reduce power output of transmitters that are over 1W. It has automatic, RF sensed TR switching and can also be remotely keyed and locked out if needed by grounding one of two control lines. It is designed around a MRF 475/ 2SC1969 transistor along with diode controlled temperature feedback for the adjustable bias circuit to maintain the bias current at a constant level.

  • Approximately 15dB gain amplifier using 2SC1969
  • Board size: 3 x 6 inches
  • Automatic TR switching
  • Manual remote keying and lockout capability
  • Temperature compensated bias circuit for maintaining good linearity
  • Single band with elliptic low pass filter to provide good rejection of harmonics
  • Designed with user configurable input attenuation for transmitters from 100mW to ~2W
