Frequency Hopping Spread Spectrum (FHSS)
sorin-schwartz.comWLAN and WBA applications in the unlicensed spectrum use the frequency band known as “2.4 GHz” (ranging from 2.4 GHz to 2.4835 GHz, same as the Industrial, Scientific and Medical - ISM band). The operation in this band is defined by IEEE 802.11. w w w .

Frequency Multipliers - QSL.net
www.qsl.net• Using a multiplier chain (10 x 24 = 240) to get a 2.4 GHz signal, degrades this Phase Noise by 20*LOG(240) = 48 dB, yielding: -170 dBc/Hz + 48 dB = -122 dBc/Hz @ 100 kHz offset. • Compare this Phase Noise to a standard LC-tank oscillator working directly at 2.4 GHz, which has a typical Phase Noise of -100dBc/Hz @ 100 kHz offset.
