MAX2063 is a high-linearity, dual-channel digital variable-gain amplifier (VGA) from MAXIM that operates in the 50MHz to 1000MHz frequency range. The device features 24dB of gain range and 5.6dB of noise figure, making it ideal for multipath receiver and transmitter applications.
The MAX2063 is a high‑linearity, dual‑path digital variable‑gain amplifier that operates from 50 MHz to 1 GHz. Each path includes a digitally controlled attenuator selectable via SPI‑compatible or 5‑bit parallel interfaces, with rapid‑fire pre‑programmed gain states.
The device is supplied from a single +5 V or +3.3 V rail, packaged in a 48‑pin thin QFN‑EP, and is qualified for an extended temperature range of –40 °C to +85 °C. Detailed electrical characteristics, typical operating curves, and layout recommendations are provided for designers.
