Preliminary Technical Data
EVALUATION BOARD
The basic connections for operating the ADL5320 are shown in
Figure 9. 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 output pin. A bias
voltage of 5 V is recommended.
