ALM-1412 Typical Scattering Parameters at 25°C, Vdd = 2.85 V, Vsd = +2.6V, Idd = 8mA (typ)

The S- and Noise Parameters are measured using the PCB described in Figures 6 and 7. The PCB material is 10 mils

Rogers® RO4350. Figure 23 shows the input and output reference planes. The circuit values, with the exception of L3,

are as indicated in Figure 6.
