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.

Positive Supply Voltage. All pins should be connected to the same supply. To ensure
adequate external bypassing, connect 0.1 μF capacitors between each pin and ground.

Local Oscillator Input. 50 Ω single-ended local oscillator input. Pins must be ac-coupled.
AC-couple LOIN to ground and drive LO through LOIP.

Baseband Inputs. Differential in-phase and quadrature baseband inputs. These high
impedance inputs must be dc-biased to approximately 1.5 V dc. These inputs are not
self-biased and must be externally biased.

RF Output. Single-ended, 50 Ω, internally biased RF output. Pin must be ac-coupled to
the load.
