The HMC701LP6CE is a SiGe BiCMOS fractional-N frequency synthesizer. The synthesizer includes a 8GHz 16-bit RF N-Divider, a 24-bit delta-sigma modulator, a very low noise digital phase frequency detector (PFD), and a precision controlled charge pump. In addition the synthesizer supports an external step tuned VCO.The fractional synthesizer features an advanced delta-sigma modulator design that allows ultra-fine frequency step sizes. The synthesizer features the ability to alter both the phase-frequency detector (PFD) gain and the cycle slipping characteristics of the PFD. This feature can reduce the time to arrive at the new frequency by 50% vs. conventional PFDs. Ultra low in-close phase noise also allows wider loop bandwidths for faster frequency hopping.The synthesizer contains a built-in linear sweeper function, which allows it to perform frequency chirps with a wide variety of sweep times, polarities and dwells, all with an external or automatic sweep trigger.A General Purpose Output (GPO) bus supports the use of multiple VCOs. In addition the synthesizer has a number of auxiliary clock generation modes that can be accessed via the GPO.Applications Base Stations for Mobile Radio (GSM, PCS, DCS, CDMA, WCDMA) Wireless LANs, WiMax Communications Test Equipment CATV Equipment FMCW Sensors Automotive Radar Phased-Array Systems
