EVALUATION BOARD
The schematic of the ADL5321 evaluation board is shown in
Figure 30. This evaluation board uses 25 mil wide traces and is
made from IS410 material (lead-free version of FR4). The
evaluation board comes tuned for operation in the 2500 MHz to
2700 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 RFOUT pin. A bias voltage of 5 V is recommended.
