The ADL5201 is a digitally controlled, variable gain, wide band- The ADL5201 is powered on by applying the appropriate logic width amplifier that provides precise gain control, high IP3, and level to the PWUP pin. The quiescent current of the ADL5201 low noise figure. The excellent distortion performance and high is typically 80 mA in low power mode. When configured in high signal bandwidth make the ADL5201 an excellent gain control performance mode for more demanding applications, the quiescent device for a variety of receiver applications. The ADL5201 also current is 110 mA. When powered down, the ADL5201 consumes incorporates a low power mode option that lowers the supply less than 7 mA and offers excellent input-to-output isolation. current. The gain setting is preserved during power-down. For wide input dynamic range applications, the ADL5201 provides Fabricated on an Analog Devices, Inc., high speed SiGe process, a broad 31.5 dB gain range with 0.5 dB resolution. The gain is the ADL5201 provides precise gain adjustment capabilities with adjustable through multiple gain control interface options: parallel, good distortion performance and low phase error. The ADL5201 serial peripheral interface, and up/down. amplifier comes in a compact, thermally enhanced, 24-lead, Incorporating proprietary distortion cancellation techniques, 4 mm × 4 mm LFCSP package and operates over the temperature the ADL5201 achieves an output IP3 of greater than 47 dBm at range of −40°C to +85°C. frequencies approaching 200 MHz for most gain settings.
