Overview
The ADF4350BCPZ-RL, produced by Analog Devices Inc., is a wideband synthesizer with an integrated voltage-controlled oscillator (VCO). This device is designed for implementing fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers. It features a fundamental output frequency range of 2200 MHz to 4400 MHz and can generate RF output frequencies as low as 137.5 MHz using divide-by-1/2/4/8 or 16 circuits. The ADF4350BCPZ-RL is suitable for various high-frequency applications requiring low phase noise and flexible output configurations.
