Description: Broadband signal is amplified by the AD603 gain amplifier cascade components, to achieve the gain range of-20 ~ 60dB 5dB step can be adjusted or continuously adjustable, and in the pass band of 0 ~ 9MHz 1dB gain fluctuations in the following complementary transistor radio level follow the high power output in the 50 load the maximum output voltage RMS Vo ≥ 10V, no significant waveform distortion amplifier output signal by the RMS detector, through 10-bit A/D converter chip TLC1549, will convert the analog voltage RMS digital signal, and sent to the microcontroller and display presets to achieve the gain.
