GENERAL DESCRIPTION

This family of monolithic RF quadrature modulators is

designed for use from 869 MHz to 960 MHz and from

1805 MHz to 1990 MHz. Excellent phase accuracy and

amplitude balance enable high performance, direct RF

modulation for communications systems.

The ADL5590 and ADL5591 can be used as direct RF

modulators in digital communications systems such as those

using the Global System for Mobile Communications (GSM)

network. In addition, the devices are compatible with enhanced

data rates for GSM evolution (EDGE).
