The MAX2027 is a high-performance, digitally controlled variable-gain amplifier designed for use from 50MHz to 400MHz. It integrates a digitally controlled attenuator and a high-linearity IF amplifier in one package. The MAX2027 is ideal for applications requiring high performance and is targeted for IF signal chains to adjust gain either dynamically or as a one-time channel gain setting. 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.
The MAX2027 is a high‑performance, digitally controlled variable‑gain amplifier designed for IF signal chains from 50 MHz to 400 MHz. It integrates a digital attenuator (23 dB range, ±0.05 dB accuracy) and a fixed‑gain, high‑linearity IF amplifier in a 20‑pin TSSOP‑EP package.
Key features include 1 dB gain‑control resolution, output IP3 of 35 dBm, noise figure of 4.7 dB at maximum gain, and operation over –40 °C to +85 °C. Recommended external components, layout guidelines, and thermal considerations are provided for optimal performance.
