Data Sheet
EVALUATION BOARD
The schematic of the
Figure 39. This evaluation board uses 25 mil wide traces and is
made from FR4 material. The evaluation board comes tuned for
operation in the 2110 MHz to 2170 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.
