19-3908; Rev 0; 12/05 EVALUATION KIT AVAILABLE 1700MHz to 3000MHz High-Linearity, Low LO Leakage Base-Station Rx/Tx Mixer MAX2043 General Description Features The MAX2043 high-linearity passive upconverter or +31dBm Typical 3rd-Order Input Intercept Point downconverter mixer is designed to provide approxi-mately +31dBm of IIP3, +67dBc of LO ± 2IF spurious +23dBm Typical Input 1dB Compression Point 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,DCS, PCS, and WiMAX base-station applications. With 1900MHz to 3000MHz LO Frequency Range a 1700MHz to 3000MHz RF frequency range and a DC to 350MHz IF Frequency Range 1900MHz to 3000MHz LO frequency range, this mixeris ideal for high-side LO injection architectures. 7.5dB Typical Conversion Loss 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 inthe 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-cal 0dBm LO drive, and supply current is rated at a typ- +5V Single-Supply Operation 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-160dBc/Hz (-160dBm/Hz when transmitting 0dBm lin- Internal RF and LO Baluns for Single-Ended ear RF power). Inputs 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 -40°C to Performance Mode +85°C temperature range. Lead-Free Package Available Applications UMTS/WCDMA and 3G Base Stations DCS 1800 and EDGE Base Stations Ordering Information PCS 1900 and EDGE Base Stations PIN- PKG
