MAX2090
50MHz to 1000MHz Analog VGA with Threshold
Alarm Circuit and Error Amplifier for Level Control
General Description
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 TC = -40NC to +95NC.

Note 1: Based on junction temperature TJ = TC + (qJC x VCC x ICC). This formula can be used when the temperature of the
exposed pad is known while the device is soldered down to a PCB. See the Applications Information section for details.
The junction temperature must not exceed +150NC.
Note 2: TC is the temperature on the exposed pad of the package. TA is the ambient temperature of the device and PCB.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
PACKAGE THERMAL CHARACTERISTICS

Junction-to-Ambient Thermal Resistance qJA (Notes 3, 4)...+29NC/W
Junction-to-Case Thermal Resistance qJC (Notes 1, 4)..........7NC/W
Note 3: Junction temperature TJ = TA + (qJA x VCC x ICC). This formula can be used when the ambient temperature of the PCB is
known. The junction temperature must not exceed +150NC.
Note 4: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
