Its excellent phase accuracy and amplitude balance enable high performance intermediate frequency or direct radio frequency modulation for munication systems. The ADL5375 features a broad baseband bandwidth, along with an output gain flatness that varies no more than 1 d B from 450 MHz to 3.5 GHz. These features , coupled with a broadband output return loss of ≤- 12 d B, make the ADL5375 ideally suited for broadband zero IF or low IF-to-RF applications, FUNCTIONAL BLOCK DIAGRAM IBBP IBBN LOIP LOIN QUADRATURE PHASE SPLITTER QBBN QBBP Figure 1. RFOUT DSOP 07052-001 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 m V (ADL5375-05) and 1500 m V (ADL5375-15). The ADL5375 is fabricated using an advanced silicon-germanium bipolar process. It is available in a 24-lead, exposed paddle, leadfree, LFCSP_VQ package. Performance is specified over a - 40°C to +85°C temperature range. A lead-free evaluation board is also available. Rev.
