ALM-1612 Scattering Parameter Measurement with Vdd = 2.7V, Idd = 6mA, L2 = 2.2nH Inductor (Taiyo Yuden AQ1052N2S-T)
The S- and Noise Parameters are measured using a microstrip PCB with 10 mils Rogers® RO4350. Figure 29 shows the
input and output reference planes. The circuit values, with the exception of L3 are as indicated in Figure 6.
