The MAX2090 high-linearity analog variable-gain amplifier (VGA) is a monolithic SiGe BiCMOS attenuator, amplifier, error amplifier, and alarm circuit, designed to interface with 50Ω systems operating in the 50MHz to 1000MHz frequency range. An external analog control voltage controls the analog attenuator. The device features a gain range of -10.9dB to +26.1dB, a noise figure of 4dB, OIP3 linearity of +38dBm, and a wide RF bandwidth. Each of these features makes the device an ideal VGA for numerous receiver and transmitter applications. In addition, the device operates from a single +5.0V supply.
This device is available in a compact 20-pin TQFN package (5mm x 5mm) with an exposed pad. Electrical performance is guaranteed over the extended temperature range, from TC = -40°C to +95°C.
