1700MHz to 3000MHz High-Linearity,

Low LO Leakage Base-Station Rx/Tx Mixer

General Description

The MAX2043 high-linearity passive upconverter or

downconverter mixer is designed to provide approxi-

mately +31dBm of IIP3, +67dBc of LO ± 2IF spurious

rejection, 7.8dB of noise figure, 7.5dB of conversion

loss, and -52dBm of LO leakage for UMTS/WCDMA,

DCS, PCS, and WiMAX base-station applications. With

a 1700MHz to 3000MHz RF frequency range and a

1900MHz to 3000MHz LO frequency range, this mixer

is ideal for high-side LO injection architectures.

In addition to offering excellent linearity and noise per-

formance, the MAX2043 also yields a high level of com-

ponent integration. The MAX2043 integrates baluns in

the RF and LO ports, a dual-input LO-selectable switch,

an LO buffer, and a double-balanced mixer. The on-

chip baluns allow for a single-ended RF input for down-

conversion (or RF output for upconversion), and

single-ended LO inputs. The MAX2043 requires a typi-

cal 0dBm LO drive, and supply current is rated at a typ-

ical 108mA level. The IF port is DC-coupled, making it

ideal for direct conversion or modulation. As an upcon-

verter, the device has low output noise floor of less than

-160dBc/Hz (-160dBm/Hz when transmitting 0dBm lin-

ear RF power).

The MAX2043 is available in a 36-pin thin QFN pack-

age (6mm x 6mm) with an exposed paddle. Electrical

performance is guaranteed over the extended -40°C to

+85°C temperature range.
