Analog Devices fully integrated and ready to use translation loop (also known as an offset loop) System in Package (SiP) are used for frequency synthesis in highly jitter sensitive applications and reduces board space and complexity compared to traditional discrete translation loop solutions designed on a PCB.
Time-To-Market is significantly reduced by taking advantage of this highly integrated solution with in-package circuitry and enhanced isolation that attenuate spurious components. The isolation within the chip and between the Mixer's LO input and the rest of the signal path is done and proven on the ADF4401A.
Key Features and Benefits
● Lowest noise solution for Best-in-Class Instrumentation and highly competitive applications with sub-10 fs rms wideband jitter.
● High Integration in a small 18 mm x 18 mm LGA package.
● Low spurs and feedthrough reduced design complexity (90 dBc LO_IN to RF output; 90 dBc spurious-free dynamic range).
Applications
● Instrumentation: 5G Wideband Testers, ETM, Communications Test Equipment
● Aerospace and Defense: MilCom, Electronic Warfare
Evaluation Board
The ADF4401A can be evaluated with the EV-ADF4401ASD2Z.
