High-Dynamic-Range, Direct Up/Downconversion 1500MHz to 3000MHz Quadrature Modulator/Demodulator

General Description
The MAX2022 low-noise, high-linearity, direct conversion quadrature modulator/demodulator is designed for single and multicarrier 1500MHz to 3000MHz UMTS/WCDMA, LTE/TD-LTE, cdma2000®, and DCS/PCS base-station applications. Direct conversion architectures are advantageous since they significantly reduce transmitter or receiver cost, part count, and power consumption as compared to traditional IF-based double conversion systems.

Benefts and Features
