The excellent distortion performance and high signal bandwidth make the ADL5201 an excellent gain control device for a variety of receiver applications.
The ADL5201 also incorporates a low power mode option that lowers the supply current.
For wide input dynamic range applications, the ADL5201 provides a broad 31.
5 dB gain range with 0.
5 dB resolution.
The gain is adjustable through multiple gain control interface options: parallel, serial peripheral interface, and up/down.
Incorporating proprietary distortion cancellation techniques, the ADL5201 achieves an output IP3 of greater than 47 dBm at frequencies approaching 200 MHz for most gain settings.

09388-001 The ADL5201 is powered on by applying the appropriate logic level to the PWUP pin.
The quiescent current of the ADL5201 is typically 80 mA in low power mode.
When configured in high performance mode for more demanding applications, the quiescent current is 110 mA.
When powered down, the ADL...
