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, RoHS compliant, LFCSP. Performance

is specified over a −40°C to +85°C temperature range. A RoHS

compliant evaluation board is available.
