1.7GHz to 2.5GHz, Direct I/Q Modulator with VGA and PA Driver
General Description
The MAX2720/MAX2721 are low-cost, high-performance, direct I/Q modulators designed for use in widebandCDMA and wireless local-loop (WLL) systems. Their direct-upconversion architecture reduces system cost, ponent count, and board space pared to devices with dual-conversion architectures. The MAX2720/MAX2721 include an I/Q modulator, a variable gain amplifier (VGA), and a power amplifier .. (PA) driver. The quadrature modulator accepts differential baseband I/Q signals and directly modulates an RF carrier in the 1.7GHz to 2.1GHz range (MAX2720) or the 2.1GHz to...
