ADF4401A Translation Loop Module

Analog Devices Inc. ADF4401A Translation Loop Module is a fully integrated System-in-Package (SiP) offset module with an RF output frequency ranging from 62.5MHz to 8GHz. This module includes a Voltage Controlled Oscillator (VCO) and calibration Phase-Locked Loop (PLL) circuit. This solution reduces board space and complexity compared to traditional discrete translation loop solutions designed on a Printed Circuit Board (PCB). The ADF4401A translation loop module provides a frequency synthesis solution for engineers designing highly competitive systems. This module requires an external phase detector or Phase-Frequency Detector (PFD) and an external Local Oscillator (LO) to form a frequency synthesis solution. Typical applications include instrumentation and measurement, automated test equipment, aerospace, and defense.
