GENERAL DESCRIPTION

The ADL5375 is a broadband quadrature modulator designed for operation from 400 MHz to 6 GHz. Its excellent phase accuracy and amplitude balance enable high performance intermediate frequency or direct radio frequency modulation for communication systems. The ADL5375 features a broad baseband bandwidth, along with an output gain flatness that varies no more than 1 dB from 450 MHz to 3.8 GHz. These features, coupled with a broadband output return loss of ≤−14 dB, make the ADL5375 ideally suited for broadband zero IF or low IF-to-RF applications, broadband digital predistortion transmitters, and multiband radio designs. The ADL5375 accepts two differential baseband inputs and a single-ended LO. It generates a single-ended 50 Ω output. The two versions offer input baseband bias levels of 500 mV (ADL5375-05) and 1500 mV (ADL5375-15). The ADL5375 is fabricated using an advanced silicon-germanium bipolar process. It is available in a 24-lead, exposed paddle, Pb-free, LFCSP_VQ package. Performance is specified over a −40°C to +85°C temperature range. A Pb-free evaluation board is also available.
