VCO integrated 53.125 MHz-13.6 GHz RF synthesizers with improved noise performance
The new ADF5356, a 13.6 GHz next-generation wideband synthesizer with integrated voltage-controlled oscillator (VCO) from Analog Devices suggested for applications such as wireless infrastructure, microwave point-to-point links, electronic test and measurement, and satellite terminals. A complimentary synthesizer product, the ADF4356, operates to 6.8 GHz and is comparable in performance.
The ADF5356 synthesizes RF signals in the frequency range of 53.125 MHz to 13.6 GHz with no gaps in frequency coverage making it a multiband synthesizer saving the designer from the need of multiple band-specific VCOs/synthesizers products and thereby reducing component count, board space, and power. ADF5356 designed to offer improved PLL figures of merit (FOM), Low VCO phase noise, low integer-boundary and phase-detector spurs, and high phase-comparison frequency.
SiGe BiCMOS process based ADF5356 and ADF4356 feature VCO phase noise of -113 dBc/Hz @ 100 kHz offset at 5 GHz with integrated rms jitter of only 97 fsec (1 kHz to 20 MHz) and integer-channel noise floor of -227 dBc/Hz. The phase detector spurious levels are below -85 dBc typical, and the phase detector comparison frequency can be as high as 125 MHz.
These RF synthesizers are easy to design-in, and fully supported by ADI 's PLL synthesizer design and simulation tool ADIsimPLL. These synthesizers are pin-compatible with Analog Devices' existing ADF5355 and ADF4355 devices.
The ADF5356 and ADF4356 are specified over the -40°C to +85°C range. They operate from nominal 3.3-V analog and digital power supplies as well as 5-V charge-pump and VCO supplies, and feature 1.8-V logic-level compatibility.
