The MAX2027 high-performance, digitally controlled
variable-gain amplifier is designed for use from 50MHz
to 400MHz.
The device integrates a digitally controlled attenuator
and a high-linearity IF amplifier in one package.
Targeted for IF signal chains to adjust gain either
dynamically or as a one-time channel gain setting, the
MAX2027 is ideal for applications requiring high perfor-
mance. The attenuator provides 23dB of attenuation
range with ±0.05dB state-to-state accuracy.
The MAX2027 is available in a thermally enhanced 20-
pin TSSOP-EP package and operates over the -40°C to
+85°C temperature range.
19-2601; Rev 1; 2/04
