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.
