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
