The LTC6948 is a 6 GHz low noise fractional-N Synthesizer with an integrated VCO from Linear Technology. At the heart of the LTC6948 is an advanced fourth order delta-sigma modulator that employs intelligent noise-shaping techniques to minimize noise contribution without creating the fractionalization spurs found in most fractional-N PLLs on the market. This results in a device with the benefits of fractionalization - from frequency agility to overall improved phase noise - but without the traditional drawbacks of using a fractional-N PLL. It is ideal for wireless, test and measurement, and military applications.
