19-3918; Rev 0; 3/06 EVALUATION KIT AVAILABLE High-Dynamic-Range, Direct Up-/Downconversion 750MHz to 1200MHz Quadrature Mod/Demod MAX2021 General Description Features The MAX2021 low-noise, high-linearity, direct upcon- 750MHz to 1200MHz RF Frequency Range version/downconversion quadrature modulator/demod- Scalable Power: External Current-Setting ulator is designed for RFID handheld and portal Resistors Provide Option for Operating Device in readers, as well as single and multicarrier 750MHz to Reduced-Power/Reduced-Performance Mode 1200MHz GSM/EDGE, cdma2000®, WCDMA, andiDEN® base-station applications. Direct conversion 36-Pin, 6mm x 6mm TQFN Provides High Isolation architectures are advantageous since they significantly in a Small Package reduce transmitter or receiver cost, part count, and Modulator Operation: power consumption as compared to traditional IF-based Meets 4-Carrier WCDMA 65dBc ACLR double conversion systems. +21dBm Typical OIP3 In addition to offering excellent linearity and noise perfor-mance, the MAX2021 also yields a high level of compo- +58dBm Typical OIP2 nent integration. This device includes two matched +16.7dBm Typical OP1dB passive mixers for modulating or demodulating in-phase -32dBm Typical LO Leakage and quadrature signals, two LO mixer amplifier drivers,and an LO quadrature splitter. On-chip baluns are also 43.5dBc Typical Sideband Suppression integrated to allow for single-ended RF and LO connec- -174dBm/Hz Output Noise Density tions. As an added feature, the baseband inputs have DC to 300MHz Baseband Input Allows a Direct been matched to allow for direct interfacing to the trans- Launch DAC Interface, Eliminating the Need for mit DAC, thereby eliminating the need for costly I/Q Costly I/Q Buffer Amplifiers buffer amplifiers. DC-Coupled Input Allows Ability for Customer The MAX2021 operates from a single +5V supply. It is Offset Voltage Control available in a compact 36-pin thin QFN package (6mmx 6mm) with an exposed paddle.
