In applications such as base stations, wireless links, satellites, communications, and instruments, overall system performance is closely related to the phase noise characteristics of the RD synthesizer. Additionally, integration density and cost require optimization regardless of RF performance. The STW81200 is an RF synthesizer that offers industry-leading flexibility and supports multi-band, multi-standard software-defined radio (SDR) development across a wide frequency range of 50 MHz to 6 GHz to meet these needs, while providing a normalized in-band phase noise floor of -227 dBc/Hz, a VCO phase noise of -135 dBc/Hz with a 1 MHz offset from the 4.0 GHz carrier, and a noise floor of -160 dBc/Hz.

The STW81200 can freely use single 5V, 3.6V, and 3.0V power supplies and can adjust power consumption according to performance, making it widely applicable to various applications ranging from existing AC power infrastructure to battery devices.

This new synthesizer represents a natural innovation within ST's successful STW8110x product family, offering superior performance and enhanced flexibility that supports multiple bands and RF standards (logistics-related) on the same board design. Additionally, it offers excellent cost savings due to superior integration and reduced material costs.

The STW81200 is robustly designed with RF infrastructure use cases in mind.

The STW81200 is currently entering mass production expansion, and ST is supplying evaluation kits of the chip as samples in 6x6 QFP (quad flat packs). The price of the STW81200 is $6 per unit for orders of 1,000. More detailed information can be found at the following website: www.st.com/stw81200
