MAX2092ETP+

The MAX2092ETP+ from Maxim Integrated Products is a 700MHz to 2700MHz analogue VGA with threshold alarm circuit and error amplifier for level control in 20 pin TQFN package. The MAX2092 high-linearity analogue 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. It is used in microwave point to point receivers and transmitters, temperature compensation circuits, LTE applications and wireless local loop.
