Frequently Asked Questions
What output frequency range does the LTC6945IUFD#PBF cover, and how does that suit wideband RF designs?
The LTC6945IUFD#PBF synthesizes output frequencies from 0.35 GHz to 6 GHz, covering S-band, C-band, and the lower portion of the X-band, making it versatile for wideband RF instruments, wireless test benches, and multi-band communication modules.
Why is ultralow phase noise important in LTC6945IUFD#PBF-based radar or communications designs?
In radar systems, close-in phase noise directly degrades clutter suppression and target detection range; in communications receivers, it raises the noise floor and degrades EVM. The LTC6945IUFD#PBF's ultralow-spurious integer-N architecture minimizes these effects across the 0.35 GHz to 6 GHz tuning range.
How does the LTC6945IUFD#PBF compare to a fractional-N synthesizer when integer frequency steps are acceptable?
When the channel spacing is a simple integer multiple of the reference frequency, the LTC6945IUFD#PBF's integer-N topology avoids the quantization spurs and sub-fractional noise of fractional-N dividers, resulting in cleaner spectral output and simpler loop filter design for fixed-channel applications from 0.35 GHz to 6 GHz.
