STW81103

Multi-band RF frequency synthesizer with integrated VCOs

Features

■ Integer-N frequency synthesizer

■ Dual differential integrated VCOs with

automatic center frequency calibration:

– 2500 - 3050 MHz (direct output)

– 4350 - 5000 MHz (direct output)

– 1250 - 1525 MHz (internal divider by 2)

■ CATV equipment

■ Instrumentation and test equipment

■ Other wireless communication systems

Description

The STMicroelectronics STW81103 is an

integrated RF synthesizer with voltage controlled

oscillators (VCOs). Showing high performance,

high integration, low power, and multi-band

performances, STW81103 is a low cost one chip

alternative to discrete PLL and VCOs solutions.

STW81103 includes an Integer-N frequency

synthesizer and two fully integrated VCOs

featuring low phase noise performance and a

noise floor of -155dBc/Hz. The combination of

wide frequency range VCOs (thanks to center-

frequency calibration over 32 sub-bands) and

multiple output options (direct output, divided by 2

or divided by 4) allows to cover the

625 MHz-762.5 MHz, the 1087.5 MHz-1525 MHz,

the 2175 MHz-3050 MHz and the

4350 MHz-5000 MHz bands.

The STW81103 is designed with

STMicroelectronics advanced 0.35 µm SiGe

process.
