MAX2022ETX+

The MAX2022ETX+ is a high dynamic-range, direct up/ down conversion 1500MHz to 3000MHz quadrature modulator/demodulator in 36 pin TQFN package. The MAX2022 is designed for up converting differential in-phase (I) and quadrature (Q) inputs from baseband to a 1500MHz to 3000MHz RF frequency range. The device can also be used as a demodulator, down converting an RF input signal directly to baseband or an IF frequency. Applications include single and multicarrier 1500MHz to 3000MHz UMTS/WCDMA, LTE/TD-LTE, cdma2000 and DCS/PCS base stations. Direct conversion architectures are advantageous. The MAX2022 integrates internal baluns, an LO buffer, a phase splitter, two LO driver amplifiers, two matched double balanced passive mixers and a wideband quadrature combiner. Precision matching between the in-phase and quadrature channels and highly linear mixers achieves excellent dynamic range, ACLR, 1dB compression point and LO and sideband suppression.
