Abstract :
Modern communication systems are multi-band and multi-mode, therefore requiring an ultra wideband low noise signal source that may allow accessing simultaneously DCS1800, PCS 1900, and WCDMA networks by a single ultra low noise wideband VCO. An ultra low noise, low cost and power efficient VCO is reported that can be tuned over a fairly wide range of frequencies (500-2500 MHz) while maintaining low phase noise (-132 dBc/Hz @100 kHz offset) over the band. The coupled distributed resonator design approach demonstrated can satisfy the need for the present demand for multi-octave-band VCOs, and is amenable for integration in chip form
