EVALUATION BOARD
The schematic of the ADL5320 evaluation board is shown in
Figure 32. This evaluation board uses 25 mil wide traces and is
made from FR4 material. The evaluation board comes tuned for
operation in the 1805 MHz to 2140 MHz tuning band. Tuning
options for other frequency bands are also provided in Table 9.
The recommended placement for these components is provided
in Table 10. The inputs and outputs should be ac-coupled with
appropriately sized capacitors. DC bias is provided to the
amplifier via an inductor connected to the RF
voltage of 5 V is recommended.
