| Abstract: | Based on the variable gain amplifier AD603 and microprocessor MSP430F449,a programmable gain wideband amplifier system with high output voltage is designed.The voltage gain can be adjusted from 0 to 60 dB through keyboard and LCD,the 3 dB bandwidth is 15 MHz,the RMS value of minimum input voltage is 1mV and the Vpp value of maximum output voltage without distortion is 28 V after adding the 50 Ω load.The bandwidth of the system can also be chosen from 2.5 MHz,5 MHz,10 MHz and 15 MHz through keyboard. |
