GENERAL DESCRIPTION
The ADL5372 is a member of the fixed-gain quadrature modulator
(F-MOD) family designed for use from 1500 MHz to 2500 MHz.
Its excellent phase accuracy and amplitude balance enable high
performance intermediate frequency or direct radio frequency
modulation for communication systems.
The ADL5372 provides a >500 MHz, 3 dB baseband bandwidth,
making it ideally suited for use in broadband zero IF or low
IF-to-RF applications and in broadband digital predistortion
transmitters.

The ADL5372 accepts two differential baseband inputs and a
single-ended, local oscillator (LO) and generates a single-
ended output.
The ADL5372 is fabricated using the Analog Devices, Inc.
advanced silicon-germanium bipolar process. It is available in
a 24-lead, exposed-paddle, Pb-free, LFCSP. Performance is
specified over a −40°C to +85°C temperature range. A Pb-free
evaluation board is available.
