Overview
The ADF4118BRU-REEL is a high-performance RF PLL Frequency Synthesizer produced by Analog Devices Inc. This device is part of the ADF4116/ADF4117/ADF4118 family and is designed to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. It features a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, programmable A and B counters, and a dual-modulus prescaler (P/P + 1). The synthesizer operates with a power supply ranging from 2.7 V to 5.5 V and can be powered down when not in use, making it energy-efficient.
