    … The input circuit provides a lowpass pole near 31MHz, assuming a 25Ω source impedance. Larger values of source impedance will lower this pole frequency. The series resistance also satisfies the required 25Ω at the input of the ADA4899-1 in unity gain configuration. At each amplifier output is a 25Ω series resistor. The lowpass section formed by these resistors, along with the 82pF capacitors, yields a pole near 77MHz. These capacitors are as large as …

      Hi all, It is suggested in the datasheet of ADA4899 that all ground and power planes under the pins of the ADA4899-1 should be cleared of copper to prevent the formation of parasitic capacitance between the input pins to ground and the output pins to ground. But if the …
