Skyworks Solutions, Inc. has released the industry’s first suite of high performance broadband synthesizers spanning ultra wide frequency ranges from 375 MHz to 5.6 GHz. Skyworks’ new device, which is designed to cover all GSM, WCDMA and LTE frequency bands with one device, supports the world’s leading 3G and 4G base station providers including Ericsson, Huawei, ZTE, Alcatel/Lucent, and Nokia/Siemens. Leveraging state-of-the-art design techniques, Skyworks has been able to deliver very stringent requirements all on a single silicon die. The SKY73134’s performance allows radio designers to support increasing levels of voice and data traffic volumes, enables design flexibility across multiple applications, and is applicable for use in microwave-link and software-defined radios. The SKY73134 is a wideband integer-N frequency synthesizer with an approximate 6 GHz locking range. This extremely small 5 x 5 millimeter (mm) device 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 less than 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, making the SKY73134 an ideal solution for GSM/EDGE, CDMA/WCDMA and LTE base station transceivers.
