General Description
The MAX2720/MAX2721 are low-cost, high-performance, direct I/Q modulators designed for use in wideband CDMA and wireless local-loop (WLL) systems. Their direct-upconversion architecture reduces system cost, component count, and board space compared to devices with dual-conversion architectures.
