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: 40dBm (at All Gain Settings and

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 0.2dB accuracy.

50MHz)

ꢀ Noise Figure: 4.7dB at Maximum Gain

ꢀ Digitally Controlled Gain with 1dB Resolution and

0.ꢀdB 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.
