The ADL5373 is a member of the fixed gain quadrature modulator (F-MOD) family designed for use from 300 MHz to 4000 MHz. The ADL5373 provides excellent phase accuracy and low noise performance for high-quality wireless communications signals.
The ADL5373 quadrature modulator operates from 2300 MHz to 3000 MHz and is intended for WiMAX, broadband wireless access and satellite modem applications. It provides high phase accuracy, amplitude balance, and a single‑ended RF output suitable for direct‑RF or low‑IF modulation schemes.
Key specifications include a 4.75 V‑5.25 V supply range, >500 MHz 3 dB bandwidth, and a noise floor of –157 dBm/Hz. An RoHS‑compliant evaluation board is available for testing, and the device is offered in a 24‑lead LFCSP package with various ordering options.
