The ADL5201 is a digitally controlled, variable gain wide bandwidth amplifier that provides precise gain control, high IP3 and low noise figure. The excellent distortion performance and high signal bandwidth makes the ADL5201 an excellent gain control device for a variety of receiver applications.
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, or gain step up/down.
Using a high speed SiGe process and incorporating proprietary distortion cancellation techniques, the ADL5201 achieves better than 47 dBm output IP3 at frequencies approaching 200 MHz for all gain settings.
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 . It may be configured for higher quiescent current of 110 mA, in high performance power mode, for more demanding applications. When powered down, the ADL5201 consumes less than 9 mA and offers excellent input to output isolation. The gain setting is preserved when powered down.
Fabricated on an ADI’s high speed SiGe process, the ADL5201 provides precise gain adjustment capabilities with good distortion performance. The ADL5201 amplifier comes in a compact, thermally enhanced 4 mm x 4mm 24-lead LFCSP package and operates over the temperature range of −40°C to +85°C.
