The MAX2066 high-linearity digital variable-gain amplifi-

er (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 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 VGA for 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 (T
