The ADF41020 frequency synthesizer can be used to implement local oscillators as high as 18 GHz in the up conversion and down conversion sections of wireless receivers and transmitters. It consists of a low noise, digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, and high frequency programmable feedback dividers (A, B, and P). A complete phase-locked loop (PLL) can be implemented if the synthesizer is used with an external loop filter and voltage controlled oscillator (VCO). The synthesizer can be used to drive external microwave VCOs via an active loop filter. Its very high bandwidth means a frequency doubler stage can be eliminated, simplifying system architecture and reducing cost. The ADF41020 is software-compatible with the existing ADF4106/ADF4107/ADF4108 family of devices from Analog Devices, Inc. Their pinouts match very closely with the exception of the ADF41020’s single-ended RF input pin, meaning only a minor layout change is required when updating current designs.

Product Lifecycle Not Recommended for New Designs
This designates products ADI does not recommend broadly for new designs.
Evaluation Kits (1)
The EV-ADF41020EB1Z evaluation board is designed to let the user evaluate the performance of the ADF41020 frequency synthesizer for phase-locked loops (PLLs). The board contains the ADF41020 synthesizer, a 100 MHz TCXO and power supplies, USB interface, and RF output connectors. There is also an active loop filter and a 13 GHz VCO on board. The evaluation kit contains software that is compatible with Windows® XP and later versions to allow easy programming of the synthesizer.
Tools & Simulations
ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
Product Selection Guide (1)
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
