**Maximum reliable continuous input power applied to the RF, IF, and LO ports of this device is +15dBm from a 50 source.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe 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 onchip 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.
