The ADL5202 is a digitally controlled, variable gain, wide bandwidth amplifier that provides precise gain control, high output IP3, and low noise figure. The excellent distortion performance and high signal bandwidth make the ADL5202 an excellent gain control device for a variety of receiver applications. The ADL5202 also incorporates a low power mode option that lowers the supply current. 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, and up/down. Incorporating proprietary distortion cancellation techniques, the ADL5202 achieves a better than 47.5 dBm output IP3 at frequencies approaching 200 MHz for most gain settings. The ADL5202 is powered on by applying the appropriate logic level to the PWUPx pins. The quiescent current of the ADL5202 is typically 160 mA in low power mode. When configured in high performance mode for more demanding applications, the quiescent current is 210 mA. When powered down, the ADL5202 consumes less than 14 mA and offers excellent input-to-output isolation. The gain setting is preserved during power-down. Fabricated on an Analog Devices, Inc., high speed SiGe process, the ADL5202 provides precise gain adjustment capabilities with good distortion performance and low phase error. The ADL5202 amplifier comes in a compact, thermally enhanced 40-lead, 6 mm × 6 mm LFCSP package and operates over a temperature range of −40°C to +85°C.
