MAX2066ETL+T
50MHz to 1000MHz High-Linearity, Serial/Parallel-Controlled Digital VGA
General DescriptionThe MAX2066 high-linearity digital variable-gain amplifi-
er (VGA) is a monolithic SiGe BiCMOS attenuator and
amplifier designed to interface with 50Ωsystems oper-
ating in the 50MHz to 1000MHz frequency range(See
theTypical Application Circuit). The digital attenuator is
controlled as a slave peripheral using either the SPI™-
compatible interface or a parallel bus with 31dB total
adjustment range in 1dB steps. An added feature
allows “rapid-fire” gain selection between each of four
steps, preprogrammed by the user through the SPI-
compatible interface. The 2-pin control allows the user
to quickly access any one of four customized attenua-
tion states without reprogramming the SPI bus.
Because each stage has its own RF input and RF output,
this component can be configured to either optimize NF
(amplifier configured first), or OIP3 (amplifier last). The
device’s performance features include 22dB amplifier
gain (amplifier only), 5.2dB NF at maximum gain (includes
attenuator insertion loss), and a high OIP3 level of
+42.4dBm. Each of these features makes the MAX2066
an ideal VGAfor numerous receiver and transmitter
applications.
In addition, the MAX2066 operates from a single +5V
supply with full performance, or a single +3.3V supply
with slightly reduced performance, and has an
adjustable bias to trade current consumption for linearity
performance. This device is available in a compact 40-
pin thin QFN package (6mm x 6mm) with an exposed
pad. Electrical performance is guaranteed over the
extended temperature range (TC= -40°C to +85°C).

VDD= +3.3V and TC= +25°C, unless otherwise noted.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation 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.
Note 1:Based on junction temperature TJ= TC+ (θJCx VCCx ICC). This formula can be used when the temperature of the exposed
pad is known while the device is soldered down to a printed-circuit board (PCB). See the Applications Information section
for details. The junction temperature must not exceed +150°C.
Note 2:Junction temperature TJ= TA+ (θJAx VCCx ICC). This formula can be used when the ambient temperature of the PCB is
known. The junction temperature must not exceed +150°C.
Note 3:Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a 4-layer
board. For detailed information on package thermal considerations, refer to /thermal-tutorial.
Note 4:TCis the temperature on the exposed pad of the package. TAis the ambient temperature of the device and PCB.
