Pulse Gaussian signal modulation and amplification circuit

The utility model relates to the technical field of wireless communication, in particular to a pulse Gaussian signal modulation amplification circuit, which comprises a first-stage amplifier, a second-stage amplifier and an operational amplifier, the output end of the first-stage amplifier is connected with the input end of the second-stage amplifier, and the first-stage amplifier inputs single-carrier pulse signals. The input end of the operational amplifier inputs a Gaussian voltage waveform, the output end of the operational amplifier is connected with the power supply end of the second-stage amplifier, the second-stage amplifier outputs a Gaussian modulation signal, and the anti-interference capability of the signal is improved by modulating a common single-carrier pulse signal into the Gaussian modulation signal. 本实用新型涉及无线通信技术领域，尤其涉及一种脉冲高斯信号调制放大电路，包括：第一级放大器、第二级放大器和运算放大器，第一级放大器输出端连接第二级放大器输入端，第一级放大器输入单载波脉冲信号，运算放大器的输入端输入高斯电压波形，运算放大器的输出端连接第二级放大器的供电端，第二级放大器输出高斯调制信号，通过将普通的单载波脉冲信号调制为高斯调制信号，由此提高了信号的抗干扰能力。
