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.
