Broadband Synthesizers Span Wide Frequency Ranges
Thu, 03/25/2010 - 2:08pm
Skyworks Solutions introduced a suite of broadband synthesizers designed to cover all GSM, WCDMA and LTE frequency bands with one device. The SKY73134 wideband integer-N frequency synthesizer with an approximate 6 GHz locking range includes four differential VCOs which, by applying internal VCO frequency division, continuously cover the output frequency from 0.375 to 5.6 GHz. The integrated phase noise from 100 Hz to 100 kHz measures <0.6 degree rms at 960 MHz frequency. In addition, the phase noises at 100 kHz, 1 MHz and 3 MHz frequency offsets are -115 dBc/Hz, -143 dBc/Hz and 150 dBc/Hz respectively.
