Product Details

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.

    Tools & Simulations

    Design Tools


    ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.


    ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
