The basic connections for operating the ADL8101 from 10 MHz to

22 GHz are shown in Figure 121. AC-couple the input and output

of the ADL8101 with appropriately sized capacitors (such as TDK

Corporation Part Number C1005X7S1A105K050BC).

Application Circuit, 10 kHz to 200 MHz,

VDD = 5 V, IDQ = 90 mA, RBIAS = 715 Ω

The bias conditions, VDD = 5 V and IDQ = 90 mA, are the recom-

mended operating point to achieve specified performance. The gain

and return loss of this circuit are shown in Figure 119 and Figure

120 across frequencies. To set other bias conditions, adjust the

RBIAS value. Table 8 shows the recommended RBIAS values and

their associated IDQ values.
