500 MHz TO 1500 MHz Quadrature Modulator
The ADL5371 is a member of the fixed-gain quadrature modulator (F-MOD) family designed for use from 500 MHz to 1500 MHz. Its excellent phase accuracy and amplitude balance enable high performance intermediate frequency or direct radio frequency modulation for communication systems.
The ADL5371 provides a >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 ADL5371 accepts two differential baseband inputs and a single-ended local oscillator (LO) and generates a single-ended output.
The ADL5371 is fabricated using the Analog Devices, Inc. advanced silicon-germanium bipolar process. It is available in a 24-lead, exposed-paddle, Pb-free, LFCSP. Performance is specified over a −40°C to +85°C temperature range. A Pb-free evaluation board is available.

ADL5371-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.
