MAX2092
700MHz to 2700MHz Analog VGA with Threshold
Alarm Circuit and Error Amplifier for Level Control
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 linear
ity 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 pos-
sible for microwave point-to-point transmitters.
The MAX2092 operates from a single +5V supply, and
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 = -40NC to +95NC.
