Overview
The ADF4116BRU-REEL7 is a member of the ADF4116 family of RF PLL (Phase-Locked Loop) frequency synthesizers produced by Analog Devices Inc. These synthesizers are designed to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers. The device integrates a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, and programmable A and B counters, along with a dual-modulus prescaler (P/P + 1). This configuration allows for flexible and precise frequency synthesis.
