ADF4401ABCEZ

Overview

The ADF4401ABCEZ is a fully integrated system-in-package translation loop module manufactured by Analog Devices Inc. It combines a Voltage Controlled Oscillator (VCO) and a calibration Phase-Locked Loop (PLL) circuit to reduce board space and complexity. The device implements an integrated downconversion mixing stage in the feedback loop, setting the loop gain to unity and minimizing in-band phase noise. Key specifications include an RF output frequency range of 62.5 MHz to 8000 MHz and a VCO frequency range of 4 GHz to 8 GHz. Integrated RMS jitter is typically 9 fs within the 100 Hz to 100 MHz offset range, with an IF output power of 17 dBm.
