| Abstract: | A digital amplitude-frequency equalization power amplifier was presented. The amplifier incorporate preamplifier, band-stop network, digital amplitude-frequency equalizer and power amplifier circuits. Preamplifier adopted low-noise operational amplifier NE5532 to construct two stages of preamplifier circuits. Band-stop network was built by man-made inductance and other circuit component. Digital amplitude-frequency equalizer was realized by FIR filter based on the frequency sampling method. High-performance... |
