Analog Devices ADF41020 Datasheet
The ADF41020 is an 18 GHz microwave PLL synthesizer designed for use in point‑to‑point radios, VSAT, test equipment, and other wireless infrastructure. It integrates a SiGe prescaler, programmable charge pump, and dual‑modulus prescaler, and can be combined with an external loop filter and VCO to create a complete PLL.
Key features include a 1.8 V/3 V SPI‑compatible serial interface, programmable dual‑modulus prescaler (8/9, 16/17, 32/33, 64/65), and a wide operating temperature range of –40 °C to +85 °C. The datasheet details electrical specifications, pin functions, timing characteristics, noise performance, and PCB design guidelines.
