The MAX2067 high-linearity analog variable-gain amplifier (VGA) is a monolithic SiGe BiCMOS attenuator and amplifier designed to interface with 50Ω systems operating in the 50MHz to 1000MHz frequency range (see the Typical Application Circuit).
The MAX2067 high‑linearity analog variable‑gain amplifier (VGA) is a monolithic SiGe BiCMOS attenuator and amplifier designed for 50 Ω systems operating from 50 MHz to 1000 MHz. It offers 22 dB amplifier gain, 4 dB noise figure at maximum gain, and a high OIP3 of +43 dBm, making it suitable for many receiver and transmitter applications.
The device operates from a single +5 V supply (or optional +3.3 V with reduced performance) and is available in a compact 40‑pin thin QFN‑EP package. Electrical specifications are guaranteed over –40 °C to +85 °C, and the part includes an on‑chip 8‑bit DAC for analog attenuation control as well as an SPI‑compatible digital interface.
