1700MHz to 3000MHz High-Linearity, Low LO Leakage Base-Station Rx/Tx Mixer
Fully Integrated Up/Downconverter Delivers 7.5dB of Conversion Loss, 31dBm of IIP3, 7.8dB of NF, 63dBc of 2LO - 2RF Rejection, and -52dBm LO - RF Leakage While Replacing a Passive Mixer, an LO Amp, Two Baluns, an LO Switch, Plus Dozens of Discrete Components
The MAX2043 high-linearity passive upconverter or
downconverter mixer is designed to provide approximately
+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 performance,
the MAX2043 also yields a high level of component
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 downconversion
(or RF output for upconversion), and
single-ended LO inputs. The MAX2043 requires a typical
0dBm LO drive, and supply current is rated at a typical
108mA level. The IF port is DC-coupled, making it
ideal for direct conversion or modulation. As an upconverter,
the device has low output noise floor of less than
-160dBc/Hz (-160dBm/Hz when transmitting 0dBm linear
RF power).
The MAX2043 is available in a 36-pin thin QFN package
(6mm x 6mm) with an exposed paddle. Electrical
performance is guaranteed over the extended -40°C to
+85°C temperature range.
