MAX2027：IF Digitally Controlled Variable-Gain Amplifier
Lowest Noise, Highest Linearity, SiGe Integrated DVGA for Base Stations
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 performance. 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.
