ADL5320ARKZ-WP

400 MHz to 2700 MHz Pre-driver RF Amplifier

Analog Devices 

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.
