55 MHz~15 GHz broadband microwave frequency synthesizer achieves three major performances and leads comprehensively

Today, Analog Devices, Inc. announces a wideband frequency synthesizer with integrated voltage-controlled oscillator that offers breakthroughs in performance and flexibility for aerospace and defense, wireless infrastructure, microwave point-to-point links, and electronic testing Multiple market applications such as measurement, satellite terminals, etc. ADI's ADF5610 new wideband fractional-N frequency synthesizer uses a single-chip design to output RF signals from 55 MHz to 15 GHz and provides the industry's lowest phase noise. Performance. Compared to an alternative solution requiring multiple narrowband GaAs voltage controlled oscillators and phase-locked loops (PLLs), the ADF5610 consumes 50% less power, is smaller in size, and has a simpler architecture, saving material costs and reducing time to market. .

Developed in ADI's proprietary advanced SiGe BiCMOS process, the ADF5610 features high modulation bandwidth and low bit error rate. Its VCO phase noise is at the industry leading level (10 kHz operating frequency, -114 dBc/Hz at 100 kHz offset) , -165 dBc/Hz for 100 MHz offset, and the normalized phase noise floor (FOM) is also low, -229 dBc/Hz. Integrated PLL function for fast frequency hopping and lock-up time (with proper loop The filter is less than 50 μs. The phase detector spur level is typically below -45 dBc and the RF output power level is 6 dBm.

The ADF5610 wideband fractional-N frequency synthesizer makes design entry easy and fully supported by ADIsimPLLTM. ADIsimPLLTM is a comprehensive, easy-to-use PLL frequency synthesizer design and simulation tool developed by Analog Devices to evaluate phase Noise, lock-up time, jitter, and other design considerations. Customers can program the device by using an integrated SPI interface and control software.

The ADF5610 is specified over the -40°C to +85°C temperature range. It can be operated with either 3.3V analog and digital nominal power supplies, or a 5 V charge pump and VCO power supply with 1.8 V logic level compatibility. The frequency synthesizer also features hardware and software power-down modes.
