Low Noise Splitter for 100 MHz Signal

In this paper, a scheme of a low-noise splitter is proposed. For this scheme, the calculation of the SPD PN sample of operational amplifiers was performed. Based on these data, operational amplifiers with a low level of SPD PN for gain coefficients 1, 2 and 4 at a frequency of 100 MHz were selected. For these amplifiers, a simulation of the operation of the circuit was performed. To confirm the theoretical data, a mock-up board was assembled. Real measurements of SPD PN have shown that the theoretical calculation is correct.
