The MAX2091 monolithic SiGe BiCMOS upconverter IC

integrates an analog variable-gain amplifier (VGA) with

an upconverting mixer stage and image filter. The device

amplifies IF signals in the 250MHz to 450MHz range

before mixing them with an LO signal. The resulting

1735MHz to 1935MHz upconverted signal is then filtered

on-chip as the final stage of signal conditioning. For a

broadband variant that does not include the image filter,

refer to the MAX2091B.

The analog attenuator is controlled by an external analog

control voltage. Device features include 23dB gain (no

attenuation), 5.4dB NF (no attenuation, including attenu-

ator insertion loss), and +24.5dBm OIP3. Each of these

features makes the MAX2091 an ideal upconverter for

numerous transmitter applications. When paired with the

MAX2092 RF VGA, a complete 2-chip IF-RF signal con-

ditioning solution is possible for microwave point-to-point

transmitter applications.

The MAX2091 operates from a single 5V supply, and is

available in a compact 20-pin TQFN package (5mm x

5mm) with an exposed pad. Electrical performance is

guaranteed over the extended temperature range from

50MHz to 500MHz Analog VGA, 1735MHz to 1935MHz
