Skyworks Solutions SKY73134 base station synthesiser

Skyworks Solutions has introduced what it claims is the first suite of high-performance broadband synthesisers spanning ultra-wide frequency ranges from 375 MHz to 5.6 GHz. The device, designed to cover all GSM, WCDMA and LTE frequency bands, supports 3G and 4G base station providers including Ericsson, Huawei, ZTE, Alcatel/Lucent and Nokia/Siemens.

The SKY73134’s performance allows 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 device is a wideband integer-N frequency synthesiser with an approximate 6 GHz locking range and includes four differential VCOs which, by applying internal VCO frequency division, continuously covers the output frequency from 0.375 to 5.6 GHz.

Phase noise from 100 Hz to 100 kHz measures less than 0.6 degrees RMS at 960 MHz. In addition, the phase noises at 100 kHz, 1 and 3 MHz frequency offsets are -115, -143 and 150 dBc/Hz.

The synthesiser is controlled by a bi-directional read/write serial to parallel interface which allows flexible device configurations that may be locked with an external VCO or external PLL or be used as a divider chain only.

Furthermore, the device is a key building block for any radio system design including backhaul, military and satellite applications that require a combination of high-performance, low-power and multi-purpose features.
