GENERAL DESCRIPTION
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 pro-
vides 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 50 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 x 6mm 40-lead LFCSP package and
operates over the temperature range of −40°C to +85°C
