EVALUATION BOARD

The schematic of the ADL5321 evaluation board is shown in

Figure 35. 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 10. The recommended placement for

these components is provided in Table 11. 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.
