This document is the technical data sheet of Analog Devices' ADF4150 device, which introduces the function and features of the device and its application scenarios
The ADF4150 is a fractional‑N and integer‑N PLL synthesizer that requires an external VCO, loop filter, and reference. It operates from a 3.0 V to 3.6 V supply, supports 1.8 V logic, and offers programmable output power, mute function, and a 3‑wire serial interface.
The document provides full specifications, timing characteristics, absolute maximum ratings, pin configuration, typical performance data, output‑matching guidelines, and ordering information for the 4 mm × 4 mm LFCSP package.
| Supply voltage (AVop) | 3.0 V to 3.6 V |
|---|---|
| Input frequency range (REFin) | 10 MHz to 250 MHz |
| RF input frequency range | 0.5 GHz to 44 GHz |
| Output power range | -4 dBm to +5 dBm (programmable in 3 dB steps) |
| Operating temperature range | -40 °C to +85 °C |
The device operates from a supply voltage of 3.0 V to 3.6 V.
The RF output can be muted by pulling the RF Power‑Down pin (PDBer) low, which is also controllable via software.
The reference input accepts frequencies from 10 MHz up to 250 MHz.
