The ADL5202 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 ADL5202 an excellent gain control device for a variety of receiver applications.

For wide input dynamic range applications, the ADL5202 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 ADL5202 achieves better than 47 dBm output IP3 at frequencies approaching 200 MHz for all gain settings. The ADL5202 is powered on by applying the appropriate logic level to the PWUP pin. The quiescent current of the ADL5202 is typically 160 mA. It may be configured for higher quiescent current of 220 mA, in high performance power mode, for more demanding applications. When powered down, the ADL5202 consumes less than 18 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 ADL5202 provides precise gain adjustment capabilities with good distortion performance. The ADL5202 amplifier comes in a compact, thermally enhanced 6 mm x 6mm 40-lead LFCSP package and operates over the temperature range of ?40°C to +85°C.
