ADL5374:  3000 MHz to 4000 MHz Quadrature Modulator

Product Description

The ADL5374 is a member of the fixed-gain quadrature modulator (F-MOD) family designed for use from 3000 MHz to 4000 MHz. Its excellent phase accuracy and amplitude balance enable high performance intermediate frequency or direct radio frequency modulation for communications systems.

The ADL5374 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 for use in broadband digital predistortion transmitters.

The ADL5374 accepts two differential baseband inputs that are mixed with a local oscillator (LO) to generate a single- ended output.

The ADL5374 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 also available.
