Overview
The ADF4360-2BCPRL7, produced by Analog Devices Inc., is a fully integrated integer-N synthesizer and voltage-controlled oscillator (VCO). This device is designed for a center frequency of 2000 MHz, with the option to divide the frequency by 2, resulting in an RF output range of 925 MHz to 1085 MHz. It features a simple 3-wire serial interface for controlling all on-chip registers and operates with a power supply ranging from 3.0 V to 3.6 V. The device can be powered down when not in use, making it energy-efficient.
