IF Digitally Controlled Variable-Gain Amplifier
General Description
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.
Features
? 50MHz to 400MHz Frequency Range
? Variable Gain: -8dB to +15dB
? Output IP3: 35dBm (at All Gain Settings)
? Noise Figure: 4.7dB at Maximum Gain
? Digitally Controlled Gain with 1dB Resolution and
±0.05dB State-to-State Accuracy
