MAX2065ETL+
50MHz to 1000MHz High-Linearity, Serial/Parallel-Controlled Analog/Digital VGA
General Description
The MAX2065 high-linearity, analog/digital variable-
gain amplifier (VGA) is designed to operate in the
50MHz to 1000MHz frequency range with two indepen-
dent attenuators (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 attenuation states without reprogram-
ming the SPI bus. The analog attenuator is controlled
using an external voltage or through the SPI-compatible
interface using an on-chip 8-bit DAC.
Because each of the three stages has its own RF input
and RF output, this component can be configured to
either optimize NF (amplifier configured first), OIP3 (ampli-
fier last), or a compromise of NF and OIP3. The device’s
performance features include 22dB amplifier gain (ampli-
fier only), 6.5dB NF at maximum gain (includes attenuator
insertion losses), and a high OIP3 level of +42dBm. Each
of these features makes the MAX2065 an ideal VGAfor
numerous receiver and transmitter applications.
In addition, the MAX2065 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).

(Typical Application Circuit, high-current (HC) mode, VCC= +3.0V to +3.6V, TC= -40°C to +85°C. Typical values are at VCC= +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.
