Description
50MHz to 1000MHz Analog VGA with Threshold Alarm Circuit and Error Amplifier for Level Control
Manufacturer
MAXIM [Maxim Integrated Products]
Datasheet
The MAX2090 high-linearity analog variable-gain ampli-
fier (VGA) is a monolithic SiGe BiCMOS attenuator,
amplifier, error amplifier, and alarm circuit, designed to
interface with 50I systems operating in the 50MHz to
1000MHz frequency range. An external analog control
voltage controls the analog attenuator. The device fea-
tures a gain range of -10.9dB to +26.1dB, a noise figure
of 4dB, OIP3 linearity of +38dBm, and a wide RF band-
width. 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 sup-
ply.
This device is available in a compact 20-pin TQFN pack-
age (5mm x 5mm) with an exposed pad. Electrical per-
formance is guaranteed over the extended temperature
range, from T
