19-0564; Rev 0; 7/06 EVALUATION KIT AVAILABLE High-Dynamic-Range, Direct Up-/Downconversion 1500MHz to 2300MHz Quadrature Mod/Demod MAX2023 General Description Features The MAX2023 low-noise, high-linearity, direct upconver- 1500MHz to 2300MHz RF Frequency Range sion/downconversion quadrature modulator/demodulator Scalable Power: External Current-Setting is designed for single and multicarrier 1500MHz to Resistors Provide Option for Operating Device in 2300MHz DCS 1800/PCS 1900 EDGE, cdma2000®, Reduced-Power/Reduced-Performance Mode WCDMA, and PHS/PAS base-station applications. 36-Pin, 6mm x 6mm TQFN Provides High Isolation Direct conversion architectures are advantageous in a Small Package since they significantly reduce transmitter or receiver Modulator Operation: cost, part count, and power consumption as comparedto traditional IF-based double-conversion systems. Meets GSM Spurious Emission of -75dBc at600kHz Offset at P In addition to offering excellent linearity and noise perfor- OUT = +6dBm mance, the MAX2023 also yields a high level of compo- +23.5dBm Typical OIP3 nent integration. This device includes two matched +61dBm Typical OIP2 passive mixers for modulating or demodulating in-phase +16dBm Typical OP1dB and quadrature signals, two LO mixer amplifier drivers, -54dBm Typical LO Leakage and an LO quadrature splitter. On-chip baluns are alsointegrated to allow for single-ended RF and LO connec- 48dBc Typical Sideband Suppression tions. As an added feature, the baseband inputs have -165dBc/Hz Output Noise Density been matched to allow for direct interfacing to the trans- Broadband Baseband Input of 450MHz Allows a mit DAC, thereby eliminating the need for costly I/Q Direct Launch DAC Interface, Eliminating the buffer amplifiers. Need for Costly I/Q Buffer Amplifiers The MAX2023 operates from a single +5V supply. It is DC-Coupled Input Allows Ability for Offset available in a compact 36-pin thin QFN package (6mm Voltage Control x 6mm) with an exposed paddle. Electrical perfor- Demodulator Operation: mance is guaranteed over the extended -40°C to +38dBm Typical IIP3 +85°C temperature range. +59dBm Typical IIP2 Applications +30dBm Typical IP1dB
