Overview
The MAX2871ETJ+ is a high-performance frequency synthesizer produced by Analog Devices Inc./Maxim Integrated. This ultra-wideband phase-locked loop (PLL) integrates multiple voltage-controlled oscillators (VCOs) and is capable of synthesizing frequencies from 23.5MHz to 6.0GHz. It is designed to maintain superior phase noise and spurious performance, making it an ideal component for various RF and wireless applications. The device is available in a lead-free, RoHS-compliant, 5mm x 5mm, 32-pin TQFN package and operates over an extended temperature range of -40°C to +85°C.
