The ADF4108BCPZ-RL is a highly-integrated frequency synthesizer designed for wireless infrastructure applications. Developed by Analog Devices, it offers a wide frequency range, high-performance phase-locked loop (PLL) functionality, and several notable features.
Starting with its key attributes, the ADF4108BCPZ-RL has an impressive output frequency range that spans from 35 MHz to 4400 MHz. This wideband capability makes it well-suited for various wireless communication systems, including cellular base stations, microwave point-to-point links, and satellite communication systems.
One of the standout features of this integrated circuit (IC) is its phase-locked loop functionality, which enables precise frequency synthesis. It achieves this by comparing the phase and frequency of a reference input signal with a divided version of the output signal. Through the use of a high-resolution fractional-N divider, the ADF4108BCPZ-RL achieves exceptionally accurate frequency synthesis and low-phase noise performance.
The IC offers a programmable 29-bit modulus that further enhances frequency resolution. This feature allows fine-tuning of the output frequency, making it suitable for applications that require precise control over various communication standards.
Additionally, the ADF4108BCPZ-RL incorporates an advanced 6-bit RF output attenuator, providing flexibility in adjusting signal strength to meet system requirements. This attenuator allows optimization of signal power without sacrificing linearity
