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 parts are compatible with enhanced
data rates for GSM evolution (EDGE).
This family is fabricated using an advanced silicon-germanium
bipolar process from Analog Devices, Inc., and is available in a
36-lead, exposed paddle LFCSP. The devices operate from
−40°C to +85°C.
