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 attenuator 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 conditioning 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 TC = -40°C to +95°C.
