Microwave Wideband Synthesizer With Integrated VCO: ADF5610


Analog Devices offers the ADF5610 microwave wideband synthesizer with an integrated VCO. This device allows implementation of fractional-N or Integer N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. The wideband microwave voltage-controlled oscillator (VCO) design allows frequencies from 57 MHz to 14,600 MHz to be generated with an output frequency ranging from 7,300 MHz to 14,600 MHz.

The VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, 64, or 128 circuits that allows the user to generate radio frequency (RF) output frequencies as low as 57 MHz. The device features an innovative programmable performance technology that enables the ADF5610 to tailor current consumption and corresponding noise performance to individual applications by selecting either a low current consumption mode or a high-performance mode for improved phase noise performance. The ADF5610 is ideally used in wireless infrastructure, test equipment, clock generation, and aerospace and defense applications.
