MAX2043 19-3908 Rev 0 12/05 1700MHz to 3000MHz High-Linearity, Low LO Leakage Base-Station Rx/Tx Mixer General Description Features The MAX2043 high-linearity passive upconverter or +31dBm Typical 3rd-Order Input Intercept Point downconverter mixer is designed to provide approxi- +23dBm Typical Input 1dB Compression Point mately +31dBm of IIP3, +67dBc of LO 2IF spurious rejection, 7.8dB of noise figure, 7.5dB of conversion 1700MHz to 3000MHz RF Frequency Range loss, and -52dBm of LO leakage for UMTS/WCDMA, 1900MHz to 3000MHz LO Frequency Range DCS, PCS, and WiMAX base-station applications. With a 1700MHz to 3000MHz RF frequency range and a DC to 350MHz IF Frequency Range 1900MHz to 3000MHz LO frequency range, this mixer 7.5dB Typical Conversion Loss is ideal for high-side LO injection architectures. In addition to offering excellent linearity and noise per- 7.8dB Typical Noise Figure formance, the MAX2043 also yields a high level of com- -160dBc/Hz LO Noise ponent integration. The MAX2043 integrates baluns in the RF and LO ports, a dual-input LO-selectable switch, -52dBm LO Leakage at RF Port an LO buffer, and a double-balanced mixer. The on- 67dBc LO 2IF Spurious Suppression chip baluns allow for a single-ended RF input for down- conversion (or RF output for upconversion), and -3dBm to +6dBm LO Drive single-ended LO inputs. The MAX2043 requires a typi- +5V Single-Supply Operation cal 0dBm LO drive, and supply current is rated at a typ- ical 108mA level. The IF port is DC-coupled, making it Built-In SPDT LO Switch with 43dB LO1 to LO2 ideal for direct conversion or modulation. As an upcon- Isolation and 50ns Switching Time verter, the device has low output noise floor of less than Internal RF and LO Baluns for Single-Ended -160dBc/Hz (-160dBm/Hz when transmitting 0dBm lin- Inputs ear RF power). The MAX2043 is available in a 36-pin thin QFN pack- External Current-Setting Resistor Provides Option age (6mm x 6mm) with an exposed paddle. Electrical for Operating Mixer in Reduced Power/Reduced performance is guaranteed over the extended -40C to Performance Mode +85C temperature range.
