General Description
The MAX2092 high-linearity analog variable-gain amplifier (VGA) is a monolithic SiGe BiCMOS attenuator/amplifier/error amplifier with an alarm circuit designed to interface with 50I systems operating in the 700MHz to 2700MHz frequency range. The device features a gain range of +18.1dB to -22.3dB, a noise figure of 5.2dB, OIP3 linearity of +32.5dBm, and a wide RF bandwidth. Each of these features makes the device an ideal VGA for numerous receiver and transmitter applications. When paired with the MAX2091 or MAX2091B variable gain upconverter, a complete 2-chip IF-RF signal conditioning solution is possible for microwave point-to-point transmitters.
