IF Digitally Controlled Variable-Gain Amplifier  
General Description  
Features  
The MAX2027 high-performance, digitally controlled  
variable-gain amplifier is designed for use from 50MHz  
to 400MHz.  
50MHz to 400MHz Frequency Range  
Variable Gain: -8dB to +15dB  
Output IP3: 35dBm (at All Gain Settings)  
Noise Figure: 4.7dB at Maximum Gain  
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.  
Digitally Controlled Gain with 1dB Resolution and  
±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.
