APPLICATIONS Cellular communication systems GSM/EDGE, CDMA2000, W-CDMA, TD-SCDMA WiMAX/LTE broadband wireless access systems Satellite modems GENERAL DESCRIPTION The ADL5375 is a broadband quadrature modulator designed for broadband digital predistortion transmitters, and multiband operation from 400 MHz to 6 GHz. Its excellent phase accuracy radio designs. and amplitude balance enable high performance intermediate The ADL5375 accepts two differential baseband inputs and frequency or direct radio frequency modulation for commu- a single-ended LO. It generates a single-ended 50 output. nication systems. The two versions offer input baseband bias levels of 500 mV The ADL5375 features a broad baseband bandwidth, along (ADL5375-05) and 1500 mV (ADL5375-15). with an output gain flatness that varies no more than 1 dB The ADL5375 is fabricated using an advanced silicon-germanium from 450 MHz to 3.5 GHz. These features, coupled with a broad- bipolar process. It is available in a 24-lead, exposed paddle, lead- band output return loss of 12 dB, make the ADL5375 ideally free, LFCSP VQ package. Performance is specified over a 40C suited for broadband zero IF or low IF-to-RF applications, to +85C temperature range. A lead-free evaluation board is also available. Rev.
