The ADL5370 is the first in the fixed-gain quadrature modulator (F-MOD) family designed for use from 300 MHz to 1000 MHz. Its excellent phase accuracy and amplitude balance enable high performance intermediate frequency or direct radio frequency modulation for communication systems.
The ADL5370 provides a greater than 500 MHz, 3 dB baseband bandwidth, making it ideally suited for use in broadband zero IF or low IF-to-RF applications and in broadband digital predistortion transmitters.
The ADL5370 accepts two differential baseband inputs and a single-ended LO and generates a single-ended 50 Ω output.
The ADL5370 is fabricated using the Analog Devices, Inc. advanced silicon-germanium bipolar process. It is available in a 24-lead, exposed-paddle, Pb-free, LFCSP package. Performance is specified over a −40°C to +85°C temperature range. A Pb-free evaluation board is available.

Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
ADL5370-EVALZ is a 4-layer, FR4-based evaluation board. For normal operation, it requires a 5 V/300 mA power supply which should be connected to the clip leads labeled VPOS and GND. The LO and baseband inputs (which should be biased at 0.5 V) are applied to edge-mounted SMA-type RF connectors (labeled LO, IBBP, IBBN, QBBP, and QBBN). The RF output signal is available at the SMA connector labeled VOUT.

Tools & Simulations
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.
