MAX2067ETL+

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18P19-P21P22-P23
General Description
The MAX2067 high-linearity analog variable-gain ampli-
fier (VGA) is a monolithic SiGe BiCMOS attenuator and
amplifier designed to interface with 50Ω systems oper-
ating in the 50MHz to 1000MHz frequency range (see
the
Typical Application Circuit
). The analog attenuator
is controlled using an external voltage or through the
SPI™-compatible interface using an on-chip 8-bit DAC.
Because each stage has its own RF input and RF out-
put, this component can be configured to either opti-
mize NF (amplifier configured first), or OIP3 (amplifier
last). The device’s performance features include 22dB
amplifier gain (amplifier only), 4dB NF at maximum gain
(includes attenuator insertion loss), and a high OIP3
level of +43dBm. Each of these features makes the
MAX2067 an ideal VGA for numerous receiver and
transmitter applications.
In addition, the MAX2067 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 (T
C
= -40°C to +85°C).

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.
