Description

The MAX2090 high-linearity analog variable-gain amplifier (VGA) is a monolithic SiGe BiCMOS attenuator, amplifier, and RMS detector designed to interface with 50Ω systems operating in the 50MHz to 1000MHz frequency range. Either the on-board RMS power detector or an external analog control voltage controls the analog attenuator. The device features a gain range of -11.5dB to +25.5dB, 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 T_C = -40°C to +95°C.
